showreel v1.1.2 — fix broken showcase deploy arc

Fixed

• showcase.mp4 deploy arc was broken. The v1.1.0 re-render dropped the ?gate=fail query param, so the first #deploy click shipped instead of failing the gate — the whole blocked → auto-rollback → fixed → shipped story then played over an already-"Deployed" console (orphaned rollback note, "gate blocked" over a live stage, no red fail state). Re-rendered with the gate armed; verified on real frames (red blocked button + ticking rollback, then green live + 100% rollout).

Added

• assets-src/build-showcase.sh — reproducible showcase render that bakes in the required ?gate=fail param and the --width 1280 (1280×720) framing, so the reel can't be regenerated wrong again.
