experiments in a post-browser web
feat: implement URL/History unification migration
- Add item_visits table for visit tracking with chaining
- Add frecencyScore, title, domain, favicon columns to items
- Add item_groups tables for future grouping feature
- Migrate all addresses to items (not just tagged)
- Migrate visits to item_visits with preserved chaining
- Calculate initial frecency scores for all URL items
- Add new API: recordItemVisit, getItemVisits, trackNavigation, queryItemsByFrecency
- Update queryItems to support frecency/lastVisit/visitCount sorting
- Add IPC handlers for all new functions
- Update history command to use frecency-sorted items
- Create browser extension datastore.js wrapper
- Update browser extension to record visits for frecency
- Update docs/datastore.md
