Cycle 16 of 16: wires isPhaseUatPassed into the SDK query
registry as 'phase.uat-passed' (alias 'phase uat-passed').
Read-only, JSON output. Handler validates the phase argument
and adapts isPhaseUatPassed to the QueryHandler signature.
Adds INVALID_PHASE_NUM to ERROR_CODE for argument validation.
Updates command-aliases.generated.ts to keep seam coverage parity.
