🐛 Fix identity always-available fallback chain

- Agent name now falls back to config.name if [identity] section is empty
- Agent role defaults to "AI Assistant built by Gyannetra"
- User name defaults to "the User" if not set
- Removes dependency on identity_setup being completed
- Every session gets identity+memory injected into system prompt
