Cut a GitHub release for the Chrome extension — pre-flight checks, package zip, bump demo-website version refs, draft release notes with commit attribution, tag, push, create GH release with zip attached, and optionally upload to the Chrome Web Store. Also handles publishing a previously-created draft via publish-release.ps1 (with optional CWS upload). Use when user says "release", "ship a release", "cut v1.4.x", "make a GH release", "publish the draft", or asks to publish a new extension version.
