Subject: [PATCH] feat(editor): quest chain UI with editing, loading, and
 validation display

- Add chain link combo to quest creation (select next quest in chain)
- Add completion text field to quest creation form
- Quest list shows chain arrows (->chain) for linked quests
- Click quest in list to edit title, level, XP inline
- Delete button for individual quests
- Live chain validation with error display (broken refs, circular chains)
- Load Quests button alongside Save Quests
