Add --session-encrypt with CECLI_SESSION_KEY or --session-key-file, wire encrypt/decrypt through SessionManager save/load/list, and document usage. Plaintext JSON remains the default when encryption is off. Co-authored-by: Cursor <cursoragent@cursor.com>

Apply isort/black formatting on session encryption files. Give legacy test_sessions mocks explicit args (session_encrypt off, model fields) so save/load work with SessionManager encryption and Model restore paths. Co-authored-by: Cursor <cursoragent@cursor.com>

Overview
This PR introduces optional AES-256-GCM encryption for saved sessions, enhancing data security for sensitive information stored on disk. It allows users to encrypt session files using a provided key, with backward compatibility for unencrypted sessions.
Key Changes
--session-encryptand--session-key-filecommand-line arguments to enable and configure session encryption.cecli/session_crypto.pycontaining AES-256-GCM encryption and decryption logic.cecli/sessions.pyto handle encrypted and unencrypted session files during saving, loading, and listing.cryptographyas a new dependency for encryption functionality.Work Breakdown
