Bind command-channel discovery

Operation boundary

Caller: Trusted backend only
Scope: Persists discovery binding between a user and a command Channel; later /message/sync acknowledgement still depends on the current-process generation record.
Atomicity: Choose uid plus source, uids plus source, or subscribers only. At most 1000 raw recipients and a 256 KiB body; subscribers must match SEND order.
Success: Retry preserves live start and ack positions. Cross-Slot failure can be partial; retry the complete batch successfully before SEND.

Deprecated
