fix(issue-9,14): bound the R1 grace by the wall clock and keep other ls failures unknown

Round-2 review of d5a191c (planner-reviewer-claude-01, planner-reviewer-codex-01).

- delegate wrapper: the R1 idle grace and the broker_unavailable re-check
  counted only their sleeps against TIMEOUT, so python/herdr probe time plus
  fresh disk heartbeats let a job run far past --timeout (55 s for a 20 s
  budget in the new test). Both loops now end at START_TIME + TIMEOUT read
  off the clock on every pass; heartbeats extend only the idle window, and
  the herdr probe is cut off at the deadline (_within_deadline)
- document the window policy d5a191c actually implements: an agent with no
  evidence is closed ~2 x IDLE_TIMEOUT after its last wire event (Issue #6
  promised IDLE_TIMEOUT + 5 s) and heartbeats may be ~2 x IDLE_TIMEOUT apart;
  correct the claim that publish_event records a heartbeat on disk before
  the wire publish - it records right after the publish attempt
- shim ls: every failed `agent list` other than a structured
  server_not_running now exits nonzero with a "state unknown" diagnostic
  instead of reaching the list parser, where an error document on stdout
  read as an empty list and let drift A terminate live rows
- tests: stdout variants for down and unrelated errors, reconcile keeping
  herdr_confirmed False on an unrelated failure, and a wall-clock upper bound
  under continuous heartbeats and slow probes; the three new checks fail on
  d5a191c
- VERSIONS.md v4.4.2: items 3 and 6 and the test count (19)

 #### 🌟 주요 개선 사항
 1. **herdr 서버 기동 env 마커 denylist (Issue #9, `lib.sh` 쉼)**: 쉼이 `herdr --session <name> server` 를 부트스트랩할 때 세션 식별 마커만 제거한 환경을 넘긴다 — `CLAUDECODE`, `CLAUDE_CODE_CHILD_SESSION`, `CLAUDE_CODE_SESSION_ID`, `CLAUDE_CODE_SESSION_ATTENDED`, `CLAUDE_CODE_ENTRYPOINT`, `CLAUDE_PID`, `CLAUDE_CODE_MESSAGING_TOKEN`, `CLAUDE_CODE_MESSAGING_SOCKET`, `CLAUDE_CODE_BRIDGE_SESSION_ID`, `ANTIGRAVITY_CONVERSATION_ID`, `HERMES_SESSION_ID`, `GROK_SESSION_ID`, `OPENCODE_SESSION_ID`. `CLAUDE_PROJECT_DIR`·`CLAUDE_CONFIG_DIR` 등 사용자 설정은 그대로 상속된다. 상속된 `CLAUDE_CODE_CHILD_SESSION` 때문에 서브에이전트 claude 의 transcript 저장이 꺼져 resume 이 불가능하던 증상을 해소.
 2. **조회 경로 자동 기동 금지 `MAM_NO_AUTOSTART=1` (Issue #9)**: 이 값이 설정되면 쉼은 서버를 띄우지 않고 호출만 전달한다. `status.sh`·`reconcile.sh` 가 이를 export 하므로 read-only `multi-agent-mux-status` 조회가 더 이상 서버 데몬을 기동하지 않는다.
-3. **쉼 `ls` 의 "no server running" 번역 (Issue #9)**: 서버가 내려가 있으면 쉼의 `ls` 가 `no server running (herdr session <name>)` 으로 보고하고, `reconcile.sh` 는 이를 빈 서버로 판정해 `herdr_confirmed` 를 유지한다(파싱 실패로 모든 서버의 drift 감지가 멈추는 회귀 방지). 번역은 `agent list` 가 **실패**하고 그 오류 봉투의 `error.code` 가 정확히 `server_not_running` 일 때만 적용한다. 성공한 목록에 같은 문자열이 들어 있거나(예: 에이전트 이름 `server_not_running-codex`) 다른 실패인 경우는 번역하지 않으므로, 살아 있는 서버가 빈 서버로 오판되어 drift A 로 전 세션이 종료 처리되지 않고 그 밖의 실패는 종전대로 unknown(`herdr_confirmed=False`)으로 남는다.

 4. **accepted 제출의 전달 확인 `SKS_DELIVERY_GRACE_S` (Issue #14, `send_keys_safe`)**: `agent prompt --wait` 결과가 `timeout`/`agent_prompt_stalled` 이면 herdr 가 입력을 이미 수락한 것으로 보고, `SKS_DELIVERY_GRACE_S`(기본 15초) 동안 `agent_status` working, 제출 전 화면에 없던 busy 토큰(`esc to interrupt`), 제출 전 스냅샷 대비 pane 변화 중 하나를 전달 확인 신호로 인정한다. 신호가 없으면 종전대로 rc 4 로 fail-closed 하고, 그 밖의 오류(`transport_error` 등)는 accepted 로 취급하지 않는다. 단일 주입 계약(재전송 없음)은 유지된다.
 5. **래퍼 레지스트리 ack 유예 `MAM_INJECT_ACK_GRACE_S` (Issue #14, `multi-agent-mux-delegate-job`)**: `send_keys_safe` 가 전달을 확인하지 못해도 잡을 `agent_blocked` 로 닫기 전에 `MAM_INJECT_ACK_GRACE_S`(기본 10초) 동안 레지스트리를 관측하고, `pending` 이 아닌 상태(에이전트의 `started` 등)가 보이면 전달된 것으로 보고 진행한다(`_inject_acknowledged`).
-6. **R1 유예의 pane busy 토큰·디스크 heartbeat 인정 (Issue #14, `_agent_still_working`, `_recent_disk_heartbeat`)**: 구독자 idle 타임아웃 후 R1 유예가 herdr `working` 외에 pane 최근 8줄의 `esc to interrupt` 토큰, 그리고 잡 `events.log` 의 최근 이벤트(`publish_event` 가 와이어 발행 전에 로컬에 기록하는 `progress` heartbeat)도 작업 중 근거로 받아들인다. 근거가 관측될 때마다 `IDLE_TIMEOUT` 만큼의 새 창이 열리고, 한 창 내내 아무 근거도 없으면 종전대로 닫는다(벽시계 `TIMEOUT` 내). idle 타임아웃보다 긴 codex 리뷰, heartbeat 간격이 한 번 idle 창을 넘긴 리뷰, 백그라운드 셸로 테스트를 돌려 herdr 에 idle 로 보이는 creator 가 턴 도중 `deadline_timeout` 으로 닫히고 이후 `completed` 가 거부되던 문제를 방지.
