feat(e2e): stabilize Playwright chat tests for desktop + mobile

Adds comprehensive Playwright E2E coverage for the unified chat stack:

- Desktop ChatTab (canvas node → side-panel chat)
- MobileChat (direct /?m=chat&a=<id> navigation)

Fixtures:
- chat-seed.ts: external workspace creation with psql bypass for loopback
  URLs, heartbeat keeper, platform_inbound_secret pre-seed, and DB cleanup
- echo-runtime.ts: minimal A2A JSON-RPC server with workspace-side
  /internal/chat/uploads/ingest endpoint for file-attachment round-trips

Tests (12/12 passing):
- panel load, send/receive echo, history persistence
- file attachment round-trip (desktop + mobile)
- composer auto-grow (mobile)
- markdown rendering: code blocks and tables (desktop)
- activity log visibility (desktop)

Also adds missing data-testid attributes:
- chat-panel (ChatTab, MobileChat)
- workspace-card (mobile AgentCard)
- mobile-chat-cta (MobileDetail open-chat button)

CI:
- .gitea/workflows/e2e-chat.yml already present; now validated locally

+# Comprehensive Playwright E2E for the unified chat stack (desktop
+# ChatTab + mobile MobileChat). Runs on every PR that touches canvas,
+# workspace-server, or this workflow file.
+#
+# Architecture:
+#   1. Ephemeral Postgres + Redis (docker, unique container names)
+#   2. workspace-server built from source, started with
+#      MOLECULE_ENV=development (fail-open auth)
+#   3. canvas dev server (npm run dev) on :3000
+#   4. Playwright tests create workspaces via API, point them at an
+#      in-process echo runtime, and exercise the full send/receive
+#      round-trip through the browser.
+#
+# Parallel-safety: same pattern as e2e-api.yml — per-run container names
+# and ephemeral host ports so concurrent jobs on the host-network runner
+# don't collide.

+"""OFFSEC-003 regression backstop — sanitize_a2a_result invariant across all A2A tool exit points.
+
+Scope
+-----
+Every public callable in ``a2a_tools_delegation`` that returns peer-sourced content
+must pass its output through ``sanitize_a2a_result`` before returning to the agent
+context.  These tests inject boundary markers and control sequences from a
+mock-peer response and assert the returned value is the sanitized form.
+
+Test coverage for:
+  - ``tool_delegate_task``            — main sync path
+  - ``tool_delegate_task``            — queued-mode fallback path
+  - ``_delegate_sync_via_polling``    — internal polling helper
+  - ``tool_check_task_status``        — filtered delegation_id lookup
+  - ``tool_check_task_status``        — list of recent delegations
+
+Issue references: #491 (delegate_task), #537 (builtin_tools/a2a_tools.py sibling)
+
+Key sanitization facts (for test authors):
+  • _escape_boundary_markers: replaces "[A2A_RESULT_FROM_PEER]" with
+    "[/ A2A_RESULT_FROM_PEER]" and "[/A2A_RESULT_FROM_PEER]" with
+    "[/ /A2A_RESULT_FROM_PEER]". The escape form is "[/ " (bracket-space).
+    Assertion pattern: assert "[/ A2A_RESULT_FROM_PEER]" in result.
+  • Defense-in-depth injection escape patterns replace SYSTEM/OVERRIDE/
+    INSTRUCTIONS/IGNORE ALL/YOU ARE NOW with "[ESCAPED_*]" forms.
+  • Error path: when peer returns an error-prefixed string (starts with
+    _A2A_ERROR_PREFIX), the raw error text is included in the user-facing
+    "DELEGATION FAILED" message. This is intentional — errors from peers
+    are surfaced as errors, not as sanitized results.
