ci: add Claude PR review, drop @claude mention handler

[ak-bugsee]

Adds a caller for the shared review workflow in bugsee/.github (.github/workflows/claude-review.yml), and removes the per-repo claude.yml @claude mention handler where there was one.

Notes:

• The review is skipped on this PR itself: the action only runs a workflow file that is identical on the default branch. It starts working on PRs opened after this one is merged.
• Private repos need a repo-level CLAUDE_CODE_OAUTH_TOKEN secret, because the org secret is not shared with private repos on the Free plan.
• Add the deep-review label to a PR to get the review from Opus instead of Sonnet.
