add the control-ui skill #34

skills/control-ui/ does not exist on main (checked at 66a5d86). The port has no control-ui skill, so the playbooks that route browser, Electron, and web UI verification to it have nothing to load in Devin.

Expected: skills/control-ui/SKILL.md, an ordinary pstack skill next to the other skills in skills/.

Upstream source: cursor/plugins @ e73df47, cursor-team-kit/skills/control-ui/SKILL.md (blob 68484fd5418cc893a6bf40e0db45b3001dcf5947). Upstream ships only SKILL.md for this skill, with no scripts or references.

Smallest fix: copy that file verbatim to skills/control-ui/SKILL.md. Make only the changes Devin needs to load it. Do not add an attribution, a "bundled from" note, a pin, a separate plugin, or any other text that names cursor-team-kit, in the skill, README, UPSTREAM.md, manifests, or CI. The existing ci.yml skill-directory check covers the new directory with no change.

This comes from Kaitian's 2026-10-26 embedded team-kit rule: every port ships deslop, control-cli, and control-ui as ordinary skills inside its pstack plugin, and never mentions cursor-team-kit.

The fix PR should say Closes #N for this issue.
