Volta Notes

Gives Claude two operations for handling burn-after-read secrets via Volta Notes. Call create_volta_note to encrypt content locally with AES-256-GCM and get back a one-time URL, or read_volta_note to decrypt and permanently destroy a note from its URL. The encryption key lives in the URL fragment so it never hits any server. Notes are stored as ciphertext on the Internet Computer and self-destruct after a single read or seven days. Useful when you need to pass API keys or credentials to an agent without them landing in conversation history, or when an agent needs to send secrets back to you through a self-destructing link.
