fix(dispatcher+watcher): never auto-dispatch into dedicated sessions

Browse source 
Observed: tasks from filesecure/.agent-queue/inbox and SecuScan/
.agent-queue/inbox were being routed into ccl-1-conformvault and
ccl-2-scanyze whenever those sessions happened to be idle. Those are
the operator's manual interactive Claude sessions, not dispatch
targets — the auto-dispatch was (a) hijacking a Claude instance the
operator was using and (b) triggering /exit via the watcher's
completion path when the side-task finished, kicking the operator out
mid-conversation.

findFreeSession was iterating Pool.Dedicated before the autonomous
pool, so any idle dedicated session was the first candidate.

- Dispatcher.findFreeSession: remove the Dedicated loop entirely.
  Auto-dispatch is now pool-only (ccl-auto-11..20).
- Watcher.completeSession: defense-in-depth — even if a dedicated
  session ever ends up in "working" state, it is no longer /exit'd;
  just marked idle. Pool /exit behaviour unchanged (context recycle).
- Tests: new TestFindFreeSessionSkipsDedicated proves the routing;
  3 existing tests rewritten to use the autonomous pool instead of
  relying on Dedicated as a fake pool.
