Shared client for the newline-JSON accessory workers in regain-device.
Native camera workers keep their separate transport/recovery supervisor. COM
imports can append a finite binary body under the same process request guard.
Canonical native camera recovery configuration and frontend metadata.
Legacy keys/defaults and acceptance ranges remain unchanged. Proxy cameras
must not acquire these native recovery promises merely by republishing them.
Outer supervision allowances for the existing native recovery workflow.
These do not change command deadlines, retry eligibility or recovery policy.
OS process startup/retirement and executor scheduling have no strict wall-time
bound: an expired caller must still retain and drain owned worker cleanup.
Backend-independent, opt-in white balance for little-endian RAW16 Bayer frames.
Raw output is the default: AWB can estimate gains without modifying science data.
