feat(store): add TTL support and harden test coverage to 90.9%
Phase 0 -- Hardening:
- Fix SQLITE_BUSY under concurrent writes by setting SetMaxOpenConns(1)
and PRAGMA busy_timeout=5000
- Add comprehensive tests: concurrent read/write (10 goroutines),
edge cases (unicode, null bytes, SQL injection, long keys), error
paths (closed store, invalid paths, corrupt files), group isolation,
upsert verification, WAL mode verification, ErrNotFound wrapping
- Add benchmarks: Set, Get, GetAll (10K keys), file-backed Set
Phase 1 -- TTL Support:
- Add expires_at nullable column with schema migration for pre-TTL DBs
- SetWithTTL(group, key, value, duration) stores keys that auto-expire
- Lazy deletion on Get for expired keys
- Background purge goroutine (configurable interval, default 60s)
- Public PurgeExpired() method for manual cleanup
- Count, GetAll, Render all exclude expired entries
- Set clears TTL when overwriting a TTL key
Coverage: 73.1% -> 90.9% (48 tests, 0 races)
