Bartok Moltbot 8eb9eed074 feat(ux): improve /help formatting with command categories (#640)
- Organize COMMANDS into COMMANDS_BY_CATEGORY dict
- Group commands: Session, Configuration, Tools & Skills, Info, Exit
- Add visual category headers with spacing
- Maintain backwards compat via flat COMMANDS dict
- Better visual hierarchy and scannability

Before:
  /help           - Show this help message
  /tools          - List available tools
  ... (dense list)

After:
  ── Session ──
    /new           Start a new conversation
    /reset         Reset conversation only
    ...

  ── Configuration ──
    /config        Show current configuration
    ...

Closes #640
