feat(pool): add start_index so manual and auto pools can coexist

Browse source 
Production had two disjoint tmux pools named alike but for different
purposes:
  ccl-0..ccl-9           — manual/interactive sessions (operator)
  ccl-auto-11..ccl-auto-20 — autonomous dispatcher pool

Until now the daemon's loops iterated prefix + 0..Max, so with the
deployed config ("prefix: ccl-auto", min=2, max=10) the dispatcher
looked for sessions "ccl-auto0..ccl-auto9" that never existed, while
the real auto pool ccl-auto-11..20 was invisible. Net effect: no task
was ever dispatched, and killAllPoolSessions fabricated phantom
"ccl-auto0/1" sessions on each swap.

- AutonomousConfig gains StartIndex (yaml start_index, default 0).
  Behaviour is unchanged when StartIndex is 0.
- Monitor, switcher (kill + recreate), dispatcher (findFreeSession),
  and lifecycle (EnsureAll + reconcile) all iterate
  [StartIndex, StartIndex+Max) so the daemon only touches its own
  range and leaves ccl-0..ccl-9 alone.
- Production config updated to prefix: "ccl-auto-", start_index: 11,
  min: 10, max: 10 — covering the 10 real ccl-auto-11..20 sessions.
