fix: kernel communication and UX robustness

- Implement outbound OACP bridge by passing streams through cognitive loop.
- Robustify 'think' and 'dispatch-action' with salvage logic and case-insensitivity.
- Fix skill loading crashes due to undefined functions in skeletal skills.
- Update org-agent.el to cleanly manage 'Thinking...' status state.
