User-facing cache controls Cobb specifically asked for. Each
SharedPreferences-backed store now reads its cap from Settings
instead of a hardcoded constant:
- History watches: 50 / 200 / 1000 / 10k / Unlimited (was fixed 50)
- History searches: 50 / 200 / 1000 / 10k / Unlimited (was fixed 20)
- Resume positions: same options (was fixed 500)
- Search results cache: same options (was fixed 30 queries)
Each store also enforces a hard ceiling (100k for History +
Resume, 5k for SearchCache) so Unlimited doesn't OOM SP on a
hostile import.
New global Cache TTL: 1 day / 7 days / 30 days / 1 year /
Forever. Drops subs feed + search cache entries older than the
cutoff on every read. Defaults to 30 days.
Settings UI — new 'Cache & history limits' section inside the
existing Local cache block with one chip-row per cap + the TTL
chip-row + a 'Clear all caches' button that nukes FeedCache,
SearchCache, ResumePositions, History.watches, History.searches
on one tap.
