- active_trip: italy-2026-demo in site.yaml (was japan-korea-2026)
- post-form.md parent updated to /trips/italy-2026-demo/dailies
- Remove japan-korea-2026 trip pages (no real trip exists)
- Remove stale old italy-2026-demo entries/stories/GPX from git tracking
(these were leftover from before the demo-source approach)
