Agent Skills: ticket-design

D-phase skill for the ticket-writing workflow. Runs brain-surgery alignment with the user on the WORK to be done (not the technical solution — at the ticket-writing layer, D designs the work, not the implementation). Loads the Q↔R-ready bundle, drafts a design proposal (artifact chain + decision points + risk), aligns with user via firm checkpoint, handles redirects with the three-strike-foundational-reversal escalation counter from Lock 31, and writes the Design Summary into the ticket body. Hands off to ticket-structure.
