Subject: [PATCH 1/8] fix(task-board): fix session-task linkage and stuck
 workflow advancement
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three bugs fixed:

1. Orphan detection used SDK sessionIds but task.session_id stores
   clientIds — IDs never matched, so spawned tasks were never reclaimed.
   Changed getActiveSessionIds to return clientIds from the registry.

2. Spawned task sessions never got taskContext set, making them invisible
   in the session overview (no link back to the task they're working on).
   Now sets taskContext immediately after spawn.

3. When a spawned session ended (success or crash), nothing triggered
   orchestrator.tick() — the workflow stayed stuck on the completed task
   forever. Added .finally() cleanup that removes the registry entry and
   advances the orchestrator.

Also renamed clientId prefix from 'headless:' to 'task:' — these are
task-spawned sessions, not headless.

Centaur review surfaced that tick() is a no-op when the orchestrator is
paused. After spawning all tasks, the orchestrator pauses (no pending
tasks left). When a spawned session ends, .finally() must call resume()
(not tick()) to re-enter the running state and trigger orphan reclaim.

Also:
- Add failure-path test: session dies without completing → resume →
  orphan reclaim → task re-dispatched (spawnSession called twice)
- Fix happy-path test to use tick() directly instead of onTaskCompleted
- Add log warning when taskContext can't be set (sync assumption guard)

- Guard .finally() handler with goalId check to prevent overriding

- Avoid intermediate array allocation in getActiveSessionIds
- Add test: tick is a no-op when orchestrator stopped before session ends

Subject: [PATCH 7/8] fix(task-board): fix TS null check in .finally() handler

Early return when orchestratorRef is null so TypeScript can narrow
the type for subsequent method calls.

Wrap orchestrator calls in .finally() handler with try-catch to prevent
unhandled rejections on store errors. Add explicit sessionId assertion
in crash-reclaim test to guard against timing fragility.
