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)

+ * Chrome cookie importer (macOS)

+ * Reads cookies from Chrome's SQLite database and decrypts values using
+ * the encryption key stored in the macOS Keychain ("Chrome Safe Storage").
+ *
+ * Encryption scheme (macOS):
+ * - Keychain password → PBKDF2(password, salt="saltysalt", iterations=1003, keylen=16)
+ * - AES-128-CBC with IV = 16 bytes of 0x20 (space)
+ * - Encrypted values prefixed with "v10" (3 bytes)
+ *
+ * Chrome timestamps are microseconds since Jan 1, 1601 (Windows/WebKit epoch).
+ * Database is copied to a temp directory to avoid WAL lock conflicts.
