- Reuse a single SQLite connection instead of open/close per query
- Add in-memory cache for frequently accessed data (brands, models,
categories) — 1000x faster on repeated access
- Enable WAL journal mode, 8MB cache, 64MB mmap for faster reads
- Cache terminal size per render cycle to avoid repeated getmaxyx()
- Close DB connection on app exit
