can
Check if prerequisites are met before this intent can execute.
This is called during initialize before onStart. If this returns false, the command will immediately cancel itself.
Use this for:
Checking sensor states (e.g., "do we have a game piece?")
Validating subsystem readiness (e.g., "is mechanism homed?")
Safety checks (e.g., "is it safe to move?")
Return
true if the intent can execute, false to cancel
