v4.1.30

Bump dependency versions:

• @sentry/browser: ^10.43.0 → ^10.45.0
• chatsy: ^2.0.9 → ^2.0.11
• firebase: ^12.10.0 → ^12.11.0

v4.1.29

Refactor the notification subscription create/update logic to use a nested
metadata object with created/updated timestamps instead of top-level fields.

• New subscriptions now store timestamps under metadata.created and
  metadata.updated instead of separate top-level created/updated objects
• Removed shared baseData object in favor of inline data per operation
• Update path uses dot-notation ('metadata.updated') to avoid overwriting
  metadata.created when only the update timestamp needs to change

v4.1.28

Bumped version from 4.1.27 to 4.1.28. Updated chatsy from ^2.0.5 to
^2.0.8 and prepare-package from ^1.2.6 to ^2.0.7 (major version bump
with esbuild bundler). Added preparePackage.type = "copy" config.
Regenerated package-lock.json with new dependency tree.
