Update CLI chat session bridge (#697)

* feat: add CLI chat sessions with Python agent bridge

Introduce a new CLI chat mode that connects Web UI directly to Hermes
Agent's AIAgent via a Python bridge subprocess and Socket.IO, bypassing
the API Server /v1/responses path. Supports streaming, slash commands
(/new, /undo, /retry, /branch, /compress, /save, /title), interrupt,
and steer.
