PR Review: feat(frontend): remove plain - Summary - This PR removes the Plain live chat integration from the frontend. It also bundles Graphite skill infrastructure changes and Docker envoy-protocol additions. The core work (Plain removal) is clean. Issues noted below.

Frontend Changes (Plain Removal): Clean execution across all affected files. vite.engine.config.ts: liveChatPlugin function/export and unused Plugin type import removed. vite.cloud.config.ts: liveChatPlugin import gone; plugins:[] is correct since engineConfig supplies its own via mergeConfig. vite-env.d.ts: Plain global interface fully removed. help-dropdown.tsx: Live Chat item and faComments import cleanly stripped. waitForClerk.ts: Commented-out Plain setCustomerDetails code removed (good dead code cleanup). onboarding/footer.tsx: match(APP_TYPE) branch and ts-pattern import replaced with a single Feedback button. Note: cloud users previously had a Support button that opened Plain chat; they now get the same feedback modal as non-cloud users - confirm this UX change is intentional. index.html: live_chat placeholder removed. No residual Plain references found - removal is complete.

Issues:

1. PR description is empty. The template checklist was not filled in. A brief note on motivation (e.g. removing Plain as a support channel) would help reviewers and git log context.

2. Unrelated changes bundled together. This PR mixes three distinct concerns: (a) Plain removal, (b) adding envoy-protocol SDK to Dockerfiles, (c) Graphite skill reorganization. Per the project atomic PR guidelines these should ideally be separate PRs.

3. Docker envoy-protocol addition needs justification. All three Dockerfiles (cloud.Dockerfile, inspector.Dockerfile, ladle.Dockerfile) add: COPY engine/sdks/typescript/envoy-protocol/ engine/sdks/typescript/envoy-protocol/ This is unrelated to Plain removal and is unmentioned in the PR title/description. What prompted it?

4. skills-lock.json third-party source. The new lock file references withgraphite/agent-skills from GitHub. Confirm the computedHash is verified at install time and the source is pinned to mitigate supply chain risk.

Minor: Good cleanup of the graphite-is-being-a-piece-of-shit-just-merge-my-stack symlink. The new .agents/skills/graphite/SKILL.md is thorough and well-structured.

Verdict: The Plain removal is clean and complete. Main asks: fill in the PR description with motivation, and explain the Docker envoy-protocol addition (or split it into its own PR).
