Enable and fix /buddy command

The /buddy command was completely disabled by bun:bundle feature('BUDDY')
flag which evaluates to false at runtime. Removed all feature('BUDDY')
checks across the codebase to register the command, and added keyboard
event handling (q/Enter to dismiss) which was missing from the UI.
