Make slash commands easier to navigate in chat by splitting help into levels, compacting list output, and surfacing current selections for model, search, memory, and browser settings. Also route /status to the active conversation session and add an access inspector so users can understand their current command and ACL context.
Rename session info endpoint from /sessions/:id/info to /sessions/:id/status
and update frontend tab label accordingly. Add /status slash command that
displays current session metrics (message count, context usage, cache hit
rate, used skills) as formatted text in any channel.
