chore(release): v0.9.2 (#396)

Bugfix release. Since v0.9.1:

- Immich outages surface as 503 with Retry-After instead of a cacheable
  404, so a transient failure can no longer pin a broken image in a
  visitor's browser cache (#394)
- `?w=` can narrow the image tier instead of being ignored, and the tier
  is part of the ETag so the three sizes cache separately (#394)
- IMAGE_CACHE_VERSION as an escape hatch for stale browser caches after
  Immich regenerates a thumbnail (#394)
- Every rate-limited response carries Retry-After; a warning fires when
  TRUSTED_PROXY_HOPS cannot identify a client (#394)
- Admin saves that would produce an unloadable gallery.yaml are rejected
  before the write rather than reported as successful (#394)
- middleware.ts migrated to the Next 16 proxy convention (#394)
- The admin password comparison no longer leaks the password length
  through timing (#395)
- next 16.2.12, react 19.2.8, js-yaml 4.3.1, @playwright/test 1.62.1,
  and three GitHub Actions majors
