MANUAL RUN: codeSplitter release after the Alchemy queue-consumer patch (#1482) #1496

The release failed at the 3 consumer replaces (HOOKS, JOBS, LEVEL_DIGS) with QueueNotFound: the #825 move left those consumers in Alchemy state on deleted queues. #1482 patches Alchemy so deleting a consumer whose queue is gone is a no-op.

Not yet checked (needs the live release):

• After the delete, Alchemy waits for Cloudflare to stop claiming the Worker as a queue consumer. Confirm that wait finishes when the old queue is already gone and doesn't hang.
• The replace creates the 3 consumers on the current queues.
• Smoke test: /api/levels still returns the ready levels; a message through each of HOOKS, JOBS and LEVEL_DIGS is consumed.

Run: merge #1482 once CI is green, then zsh ~/release-codesplitters.sh.
