Merge branch 'main' into epic/1.0_breaking_changes

Sync main (0.3.14) into the epic. Conflict resolutions:
- Kept epic's CHANGELOG, README, package.json version (1.0.0-beta.0),
  rest_handler.ts (GET+POST resubscribe already implemented as superset
  of main's #569), and its test coverage.
- Discarded main's docs edits and 0.3.14 CHANGELOG entry (release-please
  will regenerate the next entry from commit history).
- Preserved dependabot bumps on samples (@grpc/grpc-js 1.14.3->1.14.4,
  tsx 4.19.3->4.22.4).
- Bumped root @grpc/grpc-js devDep to ^1.14.4 to keep root and samples
  workspaces on the same version and avoid TS type-identity lint errors.
- npm-publish.yml, release-please.yml, and other workflows auto-merged
  cleanly (no divergence in file content).
