* fix: make PR unlink hide auto-detected reviews
* Type the empty-content test double against the real model
The literal narrowed suppressedGitHubPR to number and typed the callback
as Mock, so neither direction was comparable and tsconfig.tc.web.json
failed on TS2352. Keeping the 'as' cast preserves checking of the fields
the double does supply.
* Add localization keys for the unlinked checks-panel state
The unlinked title, relink action, and the remote-runtime upgrade notice
introduced untranslated keys that static analysis requires in en.json.
* Advertise PR suppression capability in the transport test
The client capability list is pinned by websocket-transport.test.ts, and
adding WORKTREE_GITHUB_PR_SUPPRESSION left the expected list stale.
* Fix stale PR suppression in Checks
* fix: harden PR unlink suppression state
* refactor: extract PR unlink state handling
* fix: show PR relink recovery in source control
* fix: add unlinked PR localization
* Clarify workspace-scoped PR unlinking
