ci: retrigger CI [empty]

Same fix as applied to fix/stdio-fallback-all-environments (#778).
vi.useFakeTimers()/vi.useRealTimers() pin Date.now() so the flake
(expected '5m', got '4m' on slow runners) cannot occur.

+name: MCP Stdio Transport Regression
+
+# Regression test for molecule-ai-workspace-runtime#61:
+# asyncio.connect_read_pipe / connect_write_pipe fail with
+# ValueError: "Pipe transport is only for pipes, sockets and character devices"
+# when stdout is a regular file (openclaw capture, CI tee, debugging).
+#
+# This workflow reproduces the exact failure mode and verifies the
+# fallback to direct buffer I/O works. It runs on every PR that
+# touches the MCP server or this workflow, plus nightly cron.
+#
+# Why a separate workflow (not folded into ci.yml python-lint):
+#   - The test needs to spawn the MCP server with stdout redirected
+#     to a regular file (not a TTY/pipe), which conflicts with
+#     pytest's own capture mechanism.
+#   - It exercises the actual process spawn path (python a2a_mcp_server.py)
+#     not just unit-test mocks — closer to the real openclaw integration.
+#   - A dedicated workflow surfaces stdio-specific regressions without
+#     coupling to the broader Python test suite's coverage gate.

-"""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: inserts ZWSP (U+200B) before '[' at line-start.
-    The substring "[A2A_RESULT_FROM_PEER]" IS STILL in the output (preceded by ZWSP).
-    Assertion pattern: assert ZWSP in result.
-  • _strip_closed_blocks: removes everything after the closer.
-    Assertion pattern: assert "hidden content" not in result.
-  • 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.
