New internal/agent/secrets package: AEAD blob at /var/lib/restic-manager/secrets.enc, atomic write (os.CreateTemp + Sync + Rename), 0600. Key lives in agent.yaml as base64 (SecretsKey) — same trust boundary as the bearer token, minted on first start via EnsureSecretsKey. cmd/agent: dispatcher reads creds fresh from secrets.Load() on each job rather than from in-memory config. config.update merges the push with what's on disk and persists, so a daemon restart keeps the latest values. Legacy plaintext repo_url/repo_password in agent.yaml are silently migrated into secrets.enc on next start and stripped from the YAML on the following save. Tests: round-trip + wrong-key rejection + atomic-write post-condition for secrets; key idempotence + legacy-field parse/clear for config.
