* fix(workflow): offer recommendation instead of hard redirect when UI-SPEC.md missing When plan-phase detects frontend indicators but no UI-SPEC.md, replace the AskUserQuestion hard-exit block with an offer_next-style recommendation that displays /gsd-ui-phase as the primary next step and /gsd-plan-phase --skip-ui as the bypass option. Also registers --skip-ui as a parsed flag so it silently bypasses the UI gate.
