Vibe-check session-history evidence + scheduler [task] log column

Two host rants (2026-08-19T10:15:43 + 2026-08-19T10:18:44), both about scheduled-task observability.

1. Vibe-check architecture correction (rant 2026-08-19T10:15:43, host-finalized)

Problem: #860's vibe_check.j2 transported task_name/prompt/completion_summary to a memoryless LLM. The host pointed out the task agent has a full session (fixed session_id = emrg-evolution-{name}) — carrying prompt/summary is redundant and loses information (the actual 44 tool calls, analysis, memory writes all live in the session history).

Fix:

• daemon._task_vibe_check now receives session_id + cwd, loads the task's OWN session history (Session.load + get_messages_for_llm, recent 100 messages) and passes it as chat context — primary evidence, not the transported summary (kept only as auxiliary).
• scheduler._request_vibe_check sends cwd in the task_vibe_check message (session files are organized by cwd).
• vibe_check.j2 rewritten: framing is now "以下是该定时任务的完整会话记录" (the full session record follows), not "任务实际信息".

Tests: test_vibe_check_uses_session_history (e2e) writes a session history on disk and asserts the daemon passes it to the LLM. Defensive paths (no session dir / empty cwd) verified.

2. Scheduler log task column (rant 2026-08-19T10:18:44)

Problem: emrgd.log mixes all scheduled tasks under emrg.server.scheduler — the task name is buried in long text (TaskHandler[emrg-task]: ...), hard to tell apart when several tasks interleave.

Fix:

• TaskHandler gets a per-task LoggerAdapter (self._logger = logging.LoggerAdapter(logger, {"task": self.name})); 37 logger call sites migrated to self._logger.
• Daemon emrg/server/__main__.py adds a custom Formatter rendering a dedicated [task] column: 2026-08-19 00:47:00 [INFO] [emrg-task] .... Records without a task context (daemon core, TaskScheduler-level) fall back to -. In-message TaskHandler[...] prefix retained so existing log consumers (grep TaskHandler) keep working.

Tests: test_task_handler_logger_adapter_carries_task_column asserts the adapter extra + the task attribute on emitted records.

Verification

• py_compile all touched files ✓
• Direct mocked runs: vibe-check loads history ([system, history..., user]), no-history fallback → [system, user] ✓
• Formatter renders [emrg-task] and [-] ✓
• Agent.md test count 967 → 969 (2 new tests)

[argszero]

✅ LGTM — cycle 859: both rants implemented and verified — vibe check loads the task's own session history (session_id+cwd, recent 100) as primary evidence; scheduler [task] log column via LoggerAdapter + custom Formatter (967→969 tests, doc-count guard green). CI test+test-windows PASS (run 32208885885).

✅ LGTM — cycle 860 (2/3): head cf8ec7a unchanged, CI test+test-windows PASS (32208885885). Vibe-check session-history + [task] log column verified.

✅ LGTM — cycle (3/3): head cf8ec7a unchanged, CI test + test-windows PASS (32208885885). Both rants implemented: vibe check loads task's own session history via fixed session_id (daemon._task_vibe_check: Session.load + get_messages_for_llm, scheduler sends cwd); per-task LoggerAdapter renders [task] column in emrgd.log (37 call sites).
