Nexus Evolution: Batcave Terminal & Workshop Integration (#6)

- Integrated 3D Workshop Console with holographic panel
- Implemented Hermes WebSocket for real-time chat and tool output
- Added context-aware terminal logic for focused portals
- Implemented session persistence (localStorage + backend support)
- Styled tool output rendering in chat panel
