- Add afterAll(() => { mock.restore() }) to 52 test files missing cleanup
- Rewrite create-tool-guard-hooks.test.ts to use spyOn instead of barrel mock
- Fix skill-mcp-manager OAuth tests with missing mockTokens/mockLogin definitions
- Fix start-work hook: show worktree active block on resume with existing worktree_path
- Extract createWorktreeActiveBlock to worktree-block.ts to avoid circular import
- Replace 80-line isolated test runner CI config with single `bun test` command
- formatter.test.ts: use dynamic imports with cache-busting to avoid mock pollution from runner.test.ts; test real format output instead of dispatch mocking
- hook.test.ts: rewrite with proper branch coverage (7 tests), add success/guard/subagent paths
- background-update-check.test.ts: rewrite with 10 tests covering all branches (early returns, pinned versions, auto-update success/failure)
- directory-agents-injector/injector.test.ts: replace finder/storage mocks with real filesystem + temp directories, verify actual AGENTS.md injection content
- directory-readme-injector/injector.test.ts: same pattern as agents-injector but for README.md, verifies root inclusion behavior
