- Add secure_wipe_file() to utils/crypto.py for file overwrites + deletion
- Add secure_wipe parameter to StateManager.stop() method
- Wipes all SQLite WAL files (.db, .db-wal, .db-shm) with 3 passes
- Normal exit now calls state.stop(secure_wipe=True) to clear state database
- Falls back to regular delete if secure wipe fails
- Prevents state.db from persisting on disk after shutdown
- Add encrypt_credential_dict() and decrypt_credential_field() to utils/crypto.py
- Create utils/credential_encryption.py with encryption/decryption helpers
- Add get_credential_encryption_key() to retrieve key from Infisical at runtime
- Add emit_credential_found() wrapper for modules to use instead of direct bus.emit()
- Update all 15 modules emitting CREDENTIAL_FOUND to use encrypted wrapper
- Update 4 modules consuming CREDENTIAL_FOUND to decrypt payload before processing
- Sensitive fields (username, password, hash, token, etc.) encrypted with AES-256-GCM
- Falls back to plaintext if encryption key unavailable or encryption fails
