YeonGyu-Kim 47aa1a57ca fix(cli): surface command name in 'not yet implemented' REPL message
Add SlashCommand::slash_name() to the commands crate — returns the
canonical '/name' string for any variant. Used in the REPL's stub
catch-all arm to surface which command was typed instead of printing
the opaque 'Command registered but not yet implemented.'

Before: typing /rewind → 'Command registered but not yet implemented.'
After:  typing /rewind → '/rewind is not yet implemented in this build.'

Also update the compacts_sessions_via_slash_command test assertion to
tolerate the boundary-guard fix from 6e301c8 (removed_message_count
can be 1 or 2 depending on whether the boundary falls on a tool-result
pair). All 159 CLI + 431 runtime + 115 api tests pass.
