5c36c0f15f fix(FN-4811): scope-leak guard always allows .changeset/ paths 
The [scope-leak] reviewLevel=N enforcement=warn warning was firing on
many in-progress tasks for off-scope .changeset/FN-XXXX-*.md files (the
production signature on FN-4789, FN-4801, FN-4818 \u2014 their branches all
contained .changeset/FN-4811-*.md files from the in-progress fix stack).

By convention every task may add its own changeset entry under
.changeset/ per AGENTS.md 'Finalizing Changes' section, so .changeset/
files are now treated as always-allowed by the scope-leak guard
regardless of the task's declared file scope.

Cross-task changeset leakage is still caught by stronger downstream
guards (file-scope invariant at squash, post-merge audit) at much
higher signal-to-noise. This change only suppresses the noisy
per-execution warning that was flooding logs without adding any
defensive value.

Adds a new exported helper isAlwaysAllowedScopeLeakPath() so the
allowlist surface is easy to extend. Test coverage in
scope-leak-changeset-allowlist.test.ts.

Also (incorporated from interrupted merge state): loosens the
executing-task-lock.test.ts assertion that one losing-instance store
sees zero work-log entries rather than the brittle exact-count of
mockedCreateFnAgent invocations (the no-fn_task_done retry path can
fire on the winning instance, so the count varies).

b6df11a6a8 fix(FN-4811): process-wide executingTaskLock blocks parallel execute() across instances 
Investigating FN-4814 + FN-4811 re-failures after commit 8bef30655 (which
added per-instance synchronous this.executing.add) revealed the per-instance
guard was insufficient. FN-4809 log at 02:48:17-18 UTC:

  02:48:17  [-]                Resuming execution after unpause
  02:48:17  [-]                Step 4 (Testing & Verification) -> pending
  02:48:17  [-]                Step 4 (Testing & Verification) -> pending
  02:48:17  [6097725-y2nb]     Executor detected stale merge state ...
  02:48:18  [6097816-9gde]     Executor detected stale merge state ...

Both runs y2nb and 9gde reached executor.ts:2661 (which is INSIDE execute(),
past the synchronous this.executing.add claim). The only viable explanation
is that there is more than one TaskExecutor instance in the same Node
process (engine restart race, multi-project hybrid runtime, or similar code
path). Each instance has its own executing Set, so the per-instance guard
doesn't help.

Fix: module-level singleton executingTaskLock in active-session-registry.ts,
shared across all TaskExecutor instances. execute() synchronously tryClaim()s
the lock; if false, bails. Every existing this.executing.delete() site also
calls executingTaskLock.release(). Per-instance this.executing kept because
many other call sites use it (this.executing.has at handler gates,
stuck-detector, resumeTaskForAgent, etc.).

Test setup (resetExecutorMocks in executor-test-helpers.ts) clears the lock
between tests so process-wide state doesn't leak (executor-pause and
executor-prompt tests would otherwise show 'expected 2 createFnAgent calls
but got 0' / 'expected not called but called 3 times' flakes).

Tests:
  - executing-task-lock.test.ts: 2 cases. Key case creates TWO TaskExecutor
    instances and races them on the same task ID, asserts only ONE actually
    runs. Verified FAILS on prior code (8bef30655) and PASSES on fix.

Verification:
  - Targeted suite (4 files, 170 tests): pass.
  - pnpm --filter @fusion/engine build: clean.
  - pnpm lint: clean.
