/**
 * SQLite-backed encrypted token store for the MCP server integration.
 *
 * All token data is serialised to JSON, encrypted with AES-256-GCM, then
 * written to the `tokens` table as a BLOB. The Encryptor interface decouples
 * the encryption algorithm from the store so tests can inject deterministic
 * doubles without touching real crypto.
 *
 * Wire format for the `data` column:
 *   nonce (12 bytes) || ciphertext (N bytes) || auth tag (16 bytes)
