* fix: catch unhandled exception in POST /api/updates/check (defensive hardening) (#6180)
* fix: generate non-empty approval_id when gateway approval.request omits it (#6008) (#6168)
* chore: mark update-check try/except as defensive-only guard, drop #6086 linkage
Per maintainer review, the try/except wrapper is defense-in-depth only —
it does NOT fix#6086 (root cause is signal/process-group reaping).
Updated log message and added inline comment to make this explicit.
Leave #6086 open.
* test: isolate state-dir probes from user state
* docs(changelog): stamp #6168 approval_id, #6180 update-check guard, #6305 test isolation
