Aient CLI 0.11.21

Create native sandboxes with Billing admission

Upgrade to this release to create native customer sandboxes or claim a ready
repository sandbox with the current Aient service. The CLI binds each request
to its exact allocation identity before Billing admission. A transport retry
reuses that identity and its existing admission rather than allocating another
sandbox or reserving another hold. Older clients cannot start a new native
allocation through this admission contract.

New native sessions cost €0.15/hour for small, €0.60/hour for medium, and
€1.20/hour for large. Billing measures actual occupancy in whole seconds and
rounds the final session amount once to the nearest cent. The initial €5
reservation counts against spending limits; it is not a session cap. Sessions
continue while the user and organisation limits allow, within their finite
lease. Historical sessions keep their existing terms.

A Billing denial stops before allocation and reports that no sandbox was
created. An ambiguous create retains the exact sandbox name and recovery
command so it can be reconciled safely.
