fix(a2a-mcp): use readline() not read(65536) for pipe-safe stdio

a2a_mcp_server.py main()'s stdio read loop used
`await loop.run_in_executor(None, stdin.read, 65536)`. On a PIPE,
read(n) blocks until n bytes accumulate OR EOF. A live MCP client
(openclaw bundle-mcp, Claude Code, Cursor) sends one ~150-byte
newline-delimited request and keeps stdin OPEN waiting for the reply,
so neither condition is met: the server never parses `initialize` and
the client times out (~30s; openclaw: "MCP error -32000: Connection
closed"). This silently broke peer visibility for every pipe-spawned
MCP host while passing all existing stdio tests, which only fed stdin
from a regular file or a heredoc-pipe that CLOSES (EOF returns
immediately). readline() returns as soon as one newline-delimited
line is available — exactly the JSON-RPC framing — and is
backward-compatible with the EOF/file cases.

Root cause of the 2026-05-15 openclaw peer-visibility outage
(workspace 95744c11): the molecule MCP server could not complete the
handshake over openclaw's stdio pipe, so the agent fell back to
native sessions_list. The openclaw template adapter fix
(template-openclaw#16) works around this via HTTP transport; this
patch fixes the stdio root cause so stdio works for all CLI MCP hosts.

Regression coverage:
- tests/test_a2a_mcp_server.py::TestStdioKeepOpenPipe — spawns the
  real a2a_mcp_server.py, writes one request over a pipe, and
  DELIBERATELY keeps stdin open. FAILS (15s timeout, empty response)
  on read(65536); PASSES on readline(). Verified both directions.
- ci-mcp-stdio-transport.yml: new "pipe held OPEN, no EOF" step that
  reproduces the literal openclaw failure (the prior steps only
  exercised EOF-closing stdin, which is why the outage shipped green).

+# 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).

- *    via the Phase 2b docker-exec backend).

- *    → `/configs` (the legacy default — managed config that flows
- *    through the per-runtime indirection in
- *    workspace-server/internal/handlers/template_files_eic.go).
- *
- *  When the runtime is undefined (legacy callers that don't thread
- *  `data` through, or a workspace whose runtime field hasn't loaded
- *  yet) the default is `/configs` — matches today's behaviour, no
- *  surprise.
- *
- *  Note on `/agent-home` pre-Phase-2b: the backend short-circuits
- *  with HTTP 501 and the canonical "implementation pending" body.
- *  The tab renders empty + the error banner explains. This is by
- *  design — lets us land the canvas UX before the backend ships,
- *  per the RFC's phased rollout. The 501 is graceful: it doesn't
- *  poison error toasts or generate "workspace not found" noise.
- *

+# 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.

+// 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.

-"""Tests for ``tool_get_runtime_identity`` and ``tool_update_agent_card``.
-
-These two MCP tools close the T4-tier workspace owner-permission gaps
-reported via the canvas:
-
-  - the agent could not update its own ``agent_card`` (no MCP tool
-    wrapped the existing ``POST /registry/update-card`` endpoint);
-  - the agent could not identify which model it was running (the
-    ``MODEL`` env var is injected by ``provisioner.workspace_provision``
-    but nothing surfaced it back to the agent).
-
-Ported from molecule-ai-workspace-runtime PR#17 (mirror-only repo;
-canonical edit point per ``reference_runtime_repo_is_mirror_only``).
-Adapted to core's conventions:
-
-  * tool functions return ``str`` (JSON-encoded), matching every other
-    tool in ``a2a_tools_*`` modules. Tests ``json.loads`` to inspect.
-  * permission check ``memory.write`` runs inline in
-    ``tool_update_agent_card`` (same pattern as
-    ``a2a_tools_memory.tool_commit_memory``).
-  * ``WORKSPACE_ID`` is read directly from ``os.environ`` — core does
-    not have the runtime's validated-cache layer (``molecule_runtime.
-    builtin_tools.validation``).
