Add explicit handlers for all session ctl commands (/stop, /kill,
/compact, /clear, /rn, /cwd) and session file r/w commands (/agent,
/model, /backend) and read-only queries (/models, /backends, /usage,
/ctxsz). Ctl commands now continue past the drain loop. /rn updates
local $id/$S after rename. Unknown slash commands print an error
instead of writing garbage to ctl.
