ui: Day 4 frontend — dual-write history to SQLite + persist History rename

addToHistory, renameHistoryEntry, deleteFromHistory in src/lib/stores/page.svelte.js now dual-write to: - the in-memory `history` array (UI snappiness, unchanged) - localStorage (offline / browser-preview fallback, unchanged) - SQLite via the new Tauri commands from 1cce567 (the canonical store) The SQLite write is best-effort: failure does not lose the in-memory copy. Console-warns for diagnostic visibility. Browser-preview path correctly skips the Tauri call. HistoryPage rename flow (renameItem) now calls renameHistoryEntry, which goes through update_transcript. Closes the long-standing TODO from architecture-review.md §13: rename was UI-only, never persisted, lost on reload. On rename failure a warn-toast surfaces "your change is visible now but did not save" so the user is not surprised on next launch. NOT WIRED YET (deferred): - HistoryPage.searchQuery still filters in-memory rather than calling search_transcripts. Fine for small histories; FTS5 infrastructure is in place to upgrade when needed. - Reading initial history from SQLite on session boot. localStorage remains the cold-start source for now; SQLite catches up via dual- write. A backfill / one-time sync command can land later.
