- Update enginePaused setting docs to specify stuck-task timers are suspended while pauses are active
- Document that paused wall-clock time does not count toward taskStuckTimeoutMs, including shared globalPause windows
- Clarify that unpausing restores scheduling and grants active sessions a fresh stuck-task grace window before detection resumes
Fusion-Task-Id: FN-3538
Reviewer subprocesses were spawned via fn_review_spec / fn_review_step
even with globalPause on, because reviewer.ts had no pause awareness.
Stuck detector also kept running, treating pause-disposed sessions as
inactivity and re-queuing tasks. Pause-transition listeners only called
session.dispose(), which doesn't always interrupt an in-flight LLM
stream — letting reviewer spawns leak through after pause flipped.
- reviewer.ts: re-read settings, return UNAVAILABLE without spawning
when globalPause/enginePaused is on.
- stuck-task-detector.ts: skip checkStuckTasks() while paused.
- triage.ts / executor.ts: call session.abort() before dispose() in the
pause-transition listener to interrupt in-flight work.

- Add step-scoped tracking key support in StuckTaskDetector for step-session mode
- Update tracking keys to include step session IDs when runStepsInNewSessions is enabled
- Add tests for step-scoped tracking behavior in executor and stuck-task-detector
- Ensure stuck task detection works correctly with per-step retry recovery
In step-session mode each step is registered with StuckTaskDetector
under a compound key (e.g. "FN-1452-step-1") rather than the bare
task ID. When stuck detection fired, event.taskId was that compound
key, breaking three things simultaneously:
1. beforeRequeue("FN-1452-step-1") → store.getTask() threw (no such
task) → stuckKillCount never incremented on the real task.
2. markStuckAborted("FN-1452-step-1") → activeStepExecutors.get()
returned undefined (keyed by "FN-1452") → terminateAllSessions()
never called, other step sessions kept running.
3. stuckAborted.set("FN-1452-step-1") → executor checks
stuckAborted.has("FN-1452") → miss → stuckRequeue never set
→ task never moved to todo.
Fix: add a canonicalTaskId field to TrackedTask (defaults to the
tracking key for single-session mode where they are identical).
StepSessionExecutor now passes taskDetail.id as the third arg to
trackTask(). killAndRetry() uses entry.canonicalTaskId for all
external callbacks so they always resolve to the real task ID.

- Add ContextLimitDetector to detect agent loops via repeated tool call patterns
- Implement compact-and-resume strategy: summarize conversation and restart agent from current step
- Add loop recovery to StuckTaskDetector with configurable attempt tracking and retry limits
- Extend executor with automatic loop recovery on context limit detection
- Add loop recovery support to pi executor with same compact-and-resume pattern
- Add comprehensive tests for context-limit-detector, stuck-task-detector loop detection, executor, and pi recovery
- Add changeset for patch bump to @gsxdsm/fusion
- Update README with loop detection and recovery documentation
When the stuck task detector killed a task and immediately called
moveTask("todo"), the scheduler could re-dispatch the task before the
old execution's finally block cleared this.executing. The new execute()
call hit the guard and silently returned, stranding the task in
"in-progress" with no active session or worktree (seen on FN-810/FN-912).
Move the requeue responsibility from StuckTaskDetector.killAndRetry to
the executor's finally block, which runs after this.executing.delete().
The beforeRequeue budget check now runs before session.dispose() and its
result is passed via StuckTaskEvent.shouldRequeue → markStuckAborted().
