0.2.4.1

• Version tags now get proper GitHub Releases automatically
  (.github/workflows/release-on-tag.yml): notes come from the tag
  commit's changelog-style body, so the Releases page leads with the
  product, not plumbing. Vendor asset tags are excluded by pattern.
• The vendored Playwright assets release is created as a pre-release
  going forward (and the existing one was flagged as such): it stays
  downloadable but no longer occupies the Latest release slot.
• PW_VENDOR_REPO pin follows the repo rename to futrx-com/remote.futrx;
  the old slug only kept working through GitHub's redirect.
