* Share one Modal snapshot pool across lanes and log container placement
Each worker-pool slot key was a RemoteEngine class parameter, so Modal kept a
separate container pool and memory snapshot per lane. Restores only ever used
a same-slot snapshot, and every slot cold-booted on its own after each deploy.
Slot keys now collapse to one Comfy pool and one LLM pool. Cooldowns still
come from the full slot key, so the reserve lane stays a separate pool.
Containers now log one startup line with boot/restore kind, region, host, GPU
UUID, bound function id, and, for restores, where the snapshot was captured.

* Classify snapshot-creating boots separately from real restores
Modal resumes a booting container in place after it captures a memory
snapshot, so the restore-state file exists for the snapshot's creator too.
A snapshot origin captured by the same task is now reported as
kind=snapshot-created instead of a restore.
