Auto Clear Cache And Hist

Auto Clear Cache and History on Exit helps you keep your browsing data clean automatically.

What it does:
- Clears cache and cacheStorage automatically when the last Chrome window is closed (best effort).
- Clears browsing history automatically when the last Chrome window is closed (best effort).
- Optional: clear on startup to recover if Chrome was closed unexpectedly (crash, forced quit).
- Manual option: "Clear now" button in the extension Options page.
- Shows status in Options (last clear time, pending exit clear flag).

Notes:
- Runs locally. No network requests.
- Clearing on exit is best effort. If Chrome is killed or crashes, the extension clears on next startup if enabled.
