BB.Command.Server (bb v0.15.3)

GenServer wrapper for command callback modules.

This module manages the lifecycle of user-defined command modules, handling:

Parameter reference resolution at startup
Subscription to parameter changes
Safety state change notifications
Delegation of GenServer callbacks to user module
Result extraction and delivery to awaiting callers

Command servers are temporary - they are not restarted on crash.
