v0.4.1: Chrome cookie import, config.json, session persistence

- Add Chrome cookie importer (macOS Keychain AES-128-CBC decryption)
- Add ~/.config/browse/config.json (headless, fullscreen, stealth, preview defaults)
- Add ~/.config/browse/session.json (auto-save/restore cookies + localStorage)
- Auto-import from all browsers (Safari + Firefox + Chrome) on first launch
- Deduplicate cookies across browsers (domain+name+path key)
- Defaults: headed, fullscreen, stealth, preview all enabled
- Fix BigInt overflow for Chrome timestamps (CAST to TEXT in SQL)
