Evan LezarandDrew Newberry 662dee68eb refactor(compute): make sandbox readiness gateway-owned across all drivers (#2153)
* refactor(compute): extract create_sandbox_record and update_sandbox_record helpers

Split apply_sandbox_update_locked into named helpers to make the two
distinct paths explicit: create_sandbox_record for first-observation events
and update_sandbox_record for subsequent driver snapshots on existing sandboxes.
The dispatcher now uses a match on the existing record rather than an
early-return guard.

No behavior change.

* refactor(compute): make sandbox readiness gateway-owned across all drivers

Introduce compute_phase_components and apply_readiness_conditions to
centralise the gateway's phase composition logic. The public SandboxPhase
is now determined by combining the backend phase reported by the driver with
supervisor session presence, independent of the driver implementation.

Remove SupervisorReadiness from the driver contract. Running containers
always report BackendReady; the gateway owns the Ready decision. Rename
the dispatcher match to three arms so that status-less events for existing
sandboxes are a documented no-op rather than a silent pass-through.

Drop backend_ready_no_session and the SupervisorNotConnected condition.
The BackendReady driver condition plus the Provisioning phase already
communicates that the backend is up but the supervisor has not connected.
The redundant condition added noise without new information.

Closes #1951
