fix(canvas): keep "agent is working" indicator alive for external/poll-mode turns

External / MCP-registered workspaces (delivery_mode=poll, e.g. the local-Mac orchestrator) have no public URL: POST /workspaces/:id/a2a short-circuits server-side (a2a_proxy.go:402) and returns a synthetic {status:"queued", delivery_mode:"poll"} envelope IMMEDIATELY with no reply. useChatSend treated that as a terminal response and called releaseSendGuards() → `sending` went false the instant the POST returned → the ChatTab thinking indicator vanished and the external turn looked dead, even though the agent had not started. Internal agents reply on the same synchronous POST so their indicator naturally holds — that's the whole asymmetry; the transport is shared. Fix (Tier A, minimal, client-only): detect the synthetic poll envelope and KEEP `sending` true so the existing internal working-indicator persists as a "received — agent is working" state. The eventual reply already flows AgentMessageWriter → AGENT_MESSAGE WS push → useChatSocket onAgentMessage/onSendComplete → releaseSendGuards, i.e. the external reply now drives the indicator through the exact same path an internal async reply uses — no parallel system. A generous 15-min safety timer surfaces an honest, actionable error instead of an infinite spinner if an offline poll agent never replies. Tier B (lifecycle-driven interim progress) and Tier C (tool-call parity — has an operator-privacy tradeoff, CTO decision required) are designed in internal RFC external-workspace-canvas-progress-feedback, not in this PR.

-# WHY A DEDICATED WORKFLOW (not folded into e2e-staging-saas.yml)
-# --------------------------------------------------------------
-# This is the systemic fix for a real trust failure. Hermes and OpenClaw
-# were reported "fleet-verified / cascade-complete" because the *proxy*
-# signals were green (registry registration + heartbeat for Hermes; model
-# round-trip 200 for OpenClaw). A freshly-provisioned workspace asked on
-# canvas "can you see your peers" actually FAILS:
-#   - Hermes: 401 on the molecule MCP `list_peers` call
-#   - OpenClaw: native `sessions_list` fallback, sees no platform peers
-# Tasks #142/#159 were even marked "completed" under this proxy flaw.
-#
-# A dedicated workflow (vs extending e2e-staging-saas.yml) because:
-#   - It must provision MULTIPLE distinct runtimes (hermes, openclaw,
-#     claude-code) in ONE org and assert each sees the others. The
-#     full-saas script is single-runtime-per-run (E2E_RUNTIME) and folding
-#     a multi-runtime matrix into it would conflate concerns and bloat its
-#     already-45-min run.
-#   - It needs its own concurrency group so it doesn't fight full-saas /
-#     canvas for the staging org-creation quota.
-#   - It needs an independent, non-required status-context name so it can
-#     be RED today (the in-flight Hermes-401 / OpenClaw-MCP-wiring fixes
-#     have not landed) WITHOUT wedging unrelated merges — and flipped to
-#     REQUIRED in one branch-protection edit once it goes green
-#     (flip-to-required checklist: molecule-core#1296).
-#
-# THE ASSERTION IS NOT A PROXY. The driving script
-# tests/e2e/test_peer_visibility_mcp_staging.sh issues the byte-for-byte
-# JSON-RPC `tools/call name=list_peers` envelope to `POST
-# /workspaces/:id/mcp` using each workspace's OWN bearer token, through
-# the real WorkspaceAuth + MCPRateLimiter middleware chain — the exact
-# call mcp_molecule_list_peers makes from a canvas agent. It does NOT
-# read a registry row, /health, the heartbeat table, or
-# GET /registry/:id/peers.
-#
-# HONEST GATE — NO continue-on-error. Per feedback_fix_root_not_symptom a
-# fake-green mask would defeat the entire purpose. This workflow goes red
-# on today's broken behavior and green only when the root-cause fixes
-# actually land. It is intentionally NOT in branch_protections — see PR
-# body for the required-vs-not decision + flip tracking issue.
-#
-# Gitea 1.22.6 / act_runner notes honored:
-#   - No cross-repo `uses:` (feedback_gitea_cross_repo_uses_blocked). The
-#     actions/checkout SHA is the one e2e-staging-canvas.yml already uses
-#     successfully (a mirrored SHA — see #1277/PR#1292 root-cause).
-#   - Per-SHA concurrency, not global (feedback_concurrency_group_per_sha).
-#   - Workflow-level GITHUB_SERVER_URL pinned
-#     (feedback_act_runner_github_server_url).
-#   - pr-validate posts a status under the same check name so a
-#     workflow-only PR is not silently statusless and the context is
-#     flip-to-required-ready (mirrors e2e-staging-saas.yml's proven shape;
-#     real EC2-provisioning E2E is push/dispatch/cron only — it is 30+ min
-#     and cannot run per-PR-update).

+ * Tests for useChatSend — the canvas user→agent send hook.
+ *
+ * Behavioural focus: the poll-mode ("queued") path. When the target
+ * workspace is an external / MCP-registered agent (delivery_mode=poll,
+ * e.g. an operator laptop running the molecule MCP channel), the
+ * platform's POST /workspaces/:id/a2a returns a synthetic
+ * {status:"queued", delivery_mode:"poll"} envelope IMMEDIATELY with no
+ * reply — the real reply arrives later over the AGENT_MESSAGE
+ * WebSocket push.
+ *
+ * Pre-fix the hook treated that synthetic envelope as a terminal
+ * response and called releaseSendGuards() → `sending` went false the
+ * instant the POST returned → the "agent is working" indicator
+ * vanished and the external turn looked dead. This suite pins the
+ * fixed contract:
+ *
+ *   - a real reply still clears `sending` (regression guard)
+ *   - a poll "queued" envelope KEEPS `sending` true (no terminal
+ *     clear) so the existing thinking indicator persists
+ *   - the eventual reply path (releaseSendGuards, the same call the
+ *     AGENT_MESSAGE WS push makes via useChatSocket) clears it
+ *   - an offline poll agent that never replies eventually surfaces an
+ *     honest error instead of an infinite spinner
+ *
+ * Plus pure-function coverage for the poll-envelope detector.
+ *
+ * Root cause: workspace-server a2a_proxy.go:402 poll-mode
+ * short-circuit returns {status:"queued"} synchronously.

-# Staging E2E — fresh-provision peer-visibility gate via the LITERAL MCP path.
-#
-# WHY THIS EXISTS
-# ---------------
-# Hermes and OpenClaw were repeatedly reported "fleet-verified / cascade-
-# complete" because the *proxy* signals were green:
-#   - registry-registration + heartbeat (Hermes), and
-#   - model round-trip 200 (OpenClaw).
-# But a freshly-provisioned workspace, asked on canvas "can you see your
-# peers", actually FAILS:
-#   - Hermes: 401 on the molecule MCP `list_peers` call,
-#   - OpenClaw: falls back to native `sessions_list`, sees no platform peers.
-# Tasks #142/#159 were even marked "completed" under this same proxy flaw.
-#
-# This script codifies the LITERAL user-facing path so it can never silently
-# regress: it provisions a brand-new throwaway org + sibling workspaces via
-# the real control-plane provisioning path, then for each runtime that should
-# have platform peer-visibility it drives the EXACT MCP call the canvas agent
-# makes — `POST /workspaces/:id/mcp` JSON-RPC tools/call name=list_peers,
-# authenticated by that workspace's own bearer token through the real
-# WorkspaceAuth + MCPRateLimiter middleware chain. It then asserts:
-#   (1) HTTP 200,
-#   (2) JSON-RPC `result` present (NOT an `error` object — a -32000
-#       "tool call failed" or a 401 from WorkspaceAuth fails here),
-#   (3) the returned peer set CONTAINS the other provisioned sibling
-#       workspace IDs — not an empty list, not a native-sessions fallback.
-#
-# This is NOT a proxy. It does not look at a registry row, /health, the
-# heartbeat table, or `GET /registry/:id/peers`. It drives the byte-for-byte
-# JSON-RPC envelope that mcp_molecule_list_peers issues from a real agent.
-#
-# It is written to FAIL on today's broken Hermes/OpenClaw behavior and go
-# green only when the in-flight root-cause fixes (Hermes-401, OpenClaw MCP
-# wiring) actually land. That is the point: it is the objective proof gate.
-#
-# AUTH MODEL (mirrors tests/e2e/test_staging_full_saas.sh)
-# --------------------------------------------------------
-#   Single MOLECULE_ADMIN_TOKEN (= CP_ADMIN_API_TOKEN on Railway staging)
-#   drives: POST /cp/admin/orgs (provision), GET
-#   /cp/admin/orgs/:slug/admin-token (per-tenant token), DELETE
-#   /cp/admin/tenants/:slug (teardown). The per-tenant admin token drives
-#   tenant workspace creation; each workspace's OWN auth_token (returned by
-#   POST /workspaces) drives its MCP call.
-#
-# Required env:
-#   MOLECULE_ADMIN_TOKEN   CP admin bearer — Railway staging CP_ADMIN_API_TOKEN
-# Optional env:
-#   MOLECULE_CP_URL        default https://staging-api.moleculesai.app
-#   E2E_RUN_ID             slug suffix; CI passes ${GITHUB_RUN_ID}
-#   PV_RUNTIMES            space list; default "hermes openclaw claude-code"
-#   E2E_PROVISION_TIMEOUT_SECS  default 1800 (hermes/openclaw cold EC2 budget)
-#   E2E_MINIMAX_API_KEY / E2E_ANTHROPIC_API_KEY / E2E_OPENAI_API_KEY
-#                          LLM provider key injected so the runtime can boot
-#   E2E_KEEP_ORG           1 → skip teardown (local debugging only)
-#
-# Exit codes:
-#   0  every runtime saw its peers via the literal MCP call
-#   1  generic failure
-#   2  missing required env

-#   4  teardown left orphan resources

-// Regression coverage for the POLL-mode arm of the canvas user-message
-// data-loss bug (internal#470 sibling — tracked on internal#471).
-//
-// Bug (reported 2026-05-16 by CTO Hongming): "in canvas i sometimes lose
-// my own message when i exit chat". The push-mode arm was fixed by
-// #1347 (persistUserMessageAtIngest — a SYNCHRONOUS, before-dispatch,
-// context.WithoutCancel INSERT). #1347's framing asserted "poll-mode
-// workspaces were never affected — logA2AReceiveQueued already persists
-// at ingest". That assertion is OVERSTATED.
-//
-// Hongming's tenant (slug `hongming`, org 2c940477-...) has 4 workspaces,
-// ALL runtime=external with empty URL → ALL delivery_mode=poll (proven
-// empirically: a benign A2A probe returns the synthetic
-// {"delivery_mode":"poll","status":"queued"} envelope for every one).
-// So his reported loss is the POLL path, NOT the push path #1347 fixes.
-//
-// Root cause (poll arm): the poll-mode short-circuit (a2a_proxy.go ~402)
-// calls logA2AReceiveQueued and then IMMEDIATELY returns the synthetic
-// 200 {status:"queued"} to the canvas. But logA2AReceiveQueued's durable
-// INSERT runs inside h.goAsync(...) — a DETACHED goroutine with NO
-// happens-before barrier against the HTTP response. The canvas sees 200
-// ("message accepted") while the activity_logs row may not yet be — and,
-// on a workspace-server restart / deploy / OOM / EC2 hibernation between
-// the 200 and the goroutine's commit, NEVER will be — durable. There is
-// also no fallback (unlike push-mode's legacy-INSERT fallback): a
-// swallowed LogActivity error loses the message with only a log line.
-// Chat-history reads activity_logs (postgres_store.go:165-187); a missing
-// row = message gone on reopen. That is exactly Hongming's symptom.
-//
-// Fix (parity with push-mode): the poll-mode ingest persist of the
-// canvas user message must be SYNCHRONOUS — committed before the queued
-// 200 is returned — on a context.WithoutCancel derived context, so a
-// client disconnect on chat-exit and a post-response restart cannot lose
-// it. Behavior is never worse than today (best-effort; a persist error
-// still returns queued).
-//
-// TEST DESIGN NOTE: sqlmock.ExpectationsWereMet() hangs indefinitely if
-// the expected query never fires. We use a select+default+time.After
-// pattern so the test FAILS fast (not hangs) when the production code
-// regresses to async (the INSERT never fires before handler returns),
-// while still returning promptly when all expectations are met. The
-// insertDelay is kept small (50ms) to minimise suite-level timing
-// impact under -race detection, where mock delays are amplified by
-// the instrumenter's goroutine overhead.
