~173 `await Future<void>.delayed(Duration.zero)` async-settle waits across 25
test files yield the microtask queue exactly once; when an event→handler chain
needs more than one hop they lose the race under CI's parallel load, so the
failing set varied run to run. Replace with `await pumpEventQueue()` (the
deterministic drain already used elsewhere in the suite); rewired the shared
settle()/tick() helpers in one shot. menu_bar's toggle-close test gets a bounded
extra pump. Verified green under CI=true.

claude extension lifecycle
make test-integration failed at widget-tree finalization: the
palette's dispose() clears its scope flag, which during app teardown
runs AFTER KernelServices.dispose() has disposed the KeymapService —
notifyListeners asserted. Scope-flag mutations now use the same
fire-and-forget guard SettingsStore established. Same family in
ClaudeConfig: activation's unawaited load() could notify (and start
watchers on) a disposed notifier when a teardown raced it.
The claude extension's activation lifecycle and command success paths
are now exercised end-to-end through the kernel fixture — the file
entered the coverage denominator with the T-391 failure-path tests,
so per the ratchet discipline the rest of it gets covered too.

Sixteen claude.* handlers reported ok with an `error` field buried in
the payload — `clide claude.agent.set-permission-mode bogus` exited 0,
so scripts could not detect failure, drifting from the D-6 exit-code
contract every other subsystem honors. Missing/invalid args are now
userError, missing sessions notFound, a missing orchestrator
toolError, and a failed task reassign no longer reports ok:false as a
success. No UI consumer read the old payloads. Table-driven test
walks every failure path asserting non-zero codes.
