fix: Handle .beads/redirect files and limit verbose output in bd doctor --fix

- Add resolveBeadsDir helper to fix/common.go to follow redirect files
- Update OrphanedDependencies, ChildParentDependencies, and MergeArtifacts
  to use resolveBeadsDir instead of hardcoded .beads path
- Add --verbose/-v flag to bd doctor command
- Only print individual items if verbose or count < 20, always show summary
