feat(m9): graphical first-run setup wizard — 0.26.0

The full installer experience as a GUI wizard (gui/setup_wizard.py): environment
summary → pick dependency bundles (from the catalog, grouped) → install missing
apt packages → choose recording trigger → readiness summary.

- Shown on first launch (config setup_done) and via `rigdoctor-gui --setup`;
  re-runnable from Settings → Run setup wizard.
- install.sh launches it after a fresh install when a desktop session is present.
- catalog.by_bundle() groups components; config gains setup_done.
- Tests: by_bundle grouping + wizard construction smoke.
