Semantic Memory 2.2.0 — Ask, map, and find your memory faster

✨ New
Ask My Memory - end a search with a question mark (e.g. "how does HNSW indexing work?") and get a synthesised answer pulled from across your browsing history, with clickable sources. Fully on-device — no AI servers.
Memory Map - a brand-new tab that plots your entire knowledge space as an interactive 2D map. Related pages cluster together by topic; hover to preview, click to open.
Address-bar search - type mem then your query in the address bar to search your memory without opening the popup.
Light / Dark / Auto theme - pick one in Settings; Auto follows your system.
Backup & restore - export your full index to a file and import it back (great for moving between devices).

🔧 Improved
- Smarter search ranking that mixes meaning, keywords, titles, and recency and hides weak, unrelated matches.
- Filter results by time (all / today / week / month) and navigate them with ↑/↓ + Enter.
- Cleaner results: search-engine pages, chat apps, and webmail are no longer indexed, and revisiting a page updates it instead of creating duplicates.
- A real last-7-days activity chart, per-page delete in History and results, and a "pause indexing" switch.

🔒 Privacy
- Removed all third-party favicon requests, everything now renders locally. Still 100% on-device by default.
