chore: bump release candidate to 1.8.2 (#16718)

* chore: bump release candidate to 1.9.0

Advance the workspace candidate beyond stable v1.8.1 to match the minor release planned by the pending changelog fragments. Keep all 39 workspace lockfile entries in sync.

* fix(ci): honor planned stable release version

Keep the planned release at 1.8.2. Use a temporary prerelease baseline with the pinned changelog CLI so fragment bump levels do not override the checked-in stable candidate. Preserve the original fragment classifications and verify restoration after a failed dry run.

* chore: limit release bump to version changes

Remove the release preparation, regression test, and documentation changes as requested. Keep only the workspace and lockfile version bump to 1.8.2.
