Activate a version at a release alias

Aim one alias at one immutable version of the same agent, appending a deployment receipt in the same transaction. Moving an existing `live` pointer requires the AGENTS:DEPLOY:LIVE scope and an `If-Match` revision; preview aliases require AGENTS:DEPLOY:PREVIEW. Dependency references the version names are fingerprinted first, and an unresolvable reference refuses the activation.

Headers

The alias revision this write expects. Required on a live alias that already exists (428 without it) and refused with 412 when the stored revision has moved on. Optional on preview aliases and on the first live deployment, which has no revision yet.

idempotency-keystringOptional<=255 characters
Replay key. Repeating an activation with the same key returns the receipt the first call produced instead of moving the pointer twice.
