openenv/tbench2: drop the daytona bake CLI, which nothing can consume

       auto-stop+auto-delete TTL armed as a dead-man's switch: a keepalive
       thread beats the activity timer while the creating process lives, so

-  bake CLI (``python tb2_sandbox_daytona.py ...``)  optionally pre-register
-      named snapshots ``<prefix><task-id>`` as a warm cache.

+There is deliberately no bake step here: on this provider the image definition
+IS the cache key, so a create either hits the build cache or warms it, and
+nothing a create passes can name a pre-registered snapshot — registering one
+per task would only spend the org quota the declarative path exists to avoid.
