After a process crash or restart, tasks retain "specifying" status in the
database but no agent is actually running. These stale statuses consume
concurrency slots, blocking all new triage work. Added a startup sweep
that clears orphaned "specifying" statuses, mirroring the existing
merge status cleanup.

Tasks stuck in triage with status "specifying" had no recovery path when the
agent session crashed mid-specification (before producing an approved spec).
The stuck task detector only monitors tracked sessions, and
recoverApprovedTriageTasks only handles tasks with an approved spec — leaving
unapproved specifying tasks stranded indefinitely.
Add recoverOrphanedSpecifyingTasks to clear status back to null so the next
triage poll picks them up for a fresh specification attempt.

Multiple engine processes (dashboard + serve) share the same SQLite database
but each has its own in-memory merge queue. Without a cross-process check,
two processes can start merging different tasks simultaneously.
Added store.getActiveMergingTask() as a DB-level check before any merge
starts. The drainMergeQueue defers with pollIntervalMs delay, and both
aiMergeTask and processPullRequestMergeTask have safety-net checks.
Also moved stale merge status cleanup to run regardless of autoMerge setting.

SQLite was immediately returning SQLITE_BUSY when concurrent writes
collided (e.g., recordActivity firing from a timer during another write).
Adding a 5-second busy_timeout lets SQLite retry internally before failing.

An AI review agent (FN-1506) killed the running dashboard by finding
the process on port 4040 via lsof and running kill -9, causing exit
code 137 (SIGKILL) with no logs. This adds multi-layer guardrails:
- AGENTS.md: project-level rule reserving port 4040
- Executor/reviewer system prompts: explicit prohibition on killing
port 4040 processes, with instruction to use --port 0 instead
- Core agent-prompts.ts: same guardrails in all prompt variants
- Reviewer told to issue REVISE if executor violates the rule
- SIGHUP handlers in dashboard.ts and serve.ts for resilience
- Background engine reconciliation in dashboard/serve startup

Root cause: if a merge crashed or the process restarted mid-merge, the
"merging" status was never cleared. On next startup the stale task kept
its "merging" status while the queue moved on to the next task, resulting
in two tasks appearing to merge at once.
Two fixes:
1. Add "merging"/"merging-pr" to BLOCKING_TASK_STATUSES so tasks with
active merge status are not re-enqueued by the retry sweep.
2. Clear stale "merging" statuses during startup merge sweep — no merge
is actually running at engine start, so any such status is a leftover.

The onMerge() path (dashboard "merge now" button) bypassed the
drainMergeQueue serialization, allowing two tasks to enter "merging"
status simultaneously within the same project. Route manual merges
through the same queue so only one merge runs at a time per project.

The triage processor was only checking the global semaphore, not the
per-project maxConcurrent setting. Now it counts all active agents
(in-progress + specifying) and respects Math.min(perProjectAvailable,
semaphoreAvailable) before starting new triage tasks. This matches the
scheduler's concurrency enforcement and prevents triage from consuming
all available slots on startup.

The triage processor was kicking off all eligible tasks simultaneously,
queuing them all on the semaphore regardless of available slots. Now it
checks semaphore.availableCount first and only starts as many triage
tasks as there are free slots. Remaining tasks get picked up on the
next poll cycle (default 10-15s) as slots free up.

Both SettingsModal test files were missing mocks for fetchGlobalConcurrency
and updateGlobalConcurrency, causing the component to throw on mount.

ProjectEngineManager now creates a single AgentSemaphore and injects it
into all engines via config.globalSemaphore. Previously each engine created
its own semaphore, so the globalMaxConcurrent limit was not enforced across
projects. The semaphore dynamically reads the limit and listens for
concurrency:changed events for live updates.

they're validated by vitest at runtime, not by tsc

Remove the anti-pattern where the cwd project was treated as "primary" with a
special engine, and other projects got "secondary" engines through a separate
code path. Every project now gets an identical ProjectEngine created through
ProjectEngineManager.
Key changes:
- Add ProjectEngineManager class to @fusion/engine for uniform engine lifecycle
- Replace manual engine maps in dashboard.ts and serve.ts with engineManager
- Add engineManager to ServerOptions for per-project engine resolution
- Add getProjectContext() helper in routes.ts (replaces 199 getScopedStore calls)
- Merge and automation routes now resolve engine subsystems per-request
- SSE endpoint uses engine's store when available (same EventEmitter)
- Fix tsx not found in dev-with-memory.mjs startup script
- Add invalidateAllGlobalSettingsCaches for cross-project settings sync
