chore: bump version to 0.1.14 [skip ci]

- bump-version.yml now creates a GitHub Release with `--generate-notes`
  alongside each version tag, so the Tags/Releases page is self-describing
  instead of a bare list of vX.Y.Z tags with no context.
- README gets a Dashboard Tour gallery using the wiki's existing
  user-attachments image URLs (no binary images added to the repo).
