fix: address PR #249 review feedback

- message-builder: import PROJECT_SCOPED_TYPES from types.ts instead of
  inlining the type list, so adding a new project-scoped type won't
  silently lose its 仓库 annotation.
- message-builder: widen formatRepositoryLabel regex to capture the full
  path so nested GitLab subgroups (group/sub/repo) and trailing .git
  don't get truncated.
- scope.ts findGitDir: drop redundant statSync+dead branch; existsSync
  already covers both directory (.git/) and file (worktree .git) cases.
