feat(cli): wrap /compress in _busy_command to block input during compression

Browse source 
Before this, typing during /compress was accepted by the classic CLI
prompt and landed in the next prompt after compression finished,
effectively consuming a keystroke for a prompt that was about to be
replaced. Wrapping the body in self._busy_command('Compressing
context...') blocks input rendering for the duration, matching the
pattern /skills install and other slow commands already use.

Salvages the useful part of #10303 (@iRonin). The `_compressing` flag
added to run_agent.py in the original PR was dead code (set in 3 spots,
read nowhere — not by cli.py, not by run_agent.py, not by the Ink TUI
which doesn't use _busy_command at all) and was dropped.
