chore(ci): unblock PR #76 CI (prettier, markdownlint, docs validator)

Three pre-existing CI failures on main were gating PR #76. Fixing in
this branch rather than a separate PR per reviewer direction.

prettier
- Run `prettier --write` on .claude-plugin/marketplace.json and
  website/astro.config.mjs to restore formatting consistency.

markdownlint
- README.md: wrap the `contact@bmadcode.com` bare URL as
  <contact@bmadcode.com> (MD034/no-bare-urls).

docs:validate-links
- tools/validate-doc-links.cjs: tighten LINK_REGEX with a
  (?!\w+://) negative lookahead so external URLs ending in .md (e.g.
  https://github.com/.../CONTRIBUTING.md) are no longer incorrectly
  classified as local doc paths. The validator only knows how to
  resolve site-relative and bare .md paths; protocol URLs should be
  ignored entirely. Previously, `distribute-your-module.md`'s valid
  cross-repo marketplace CONTRIBUTING.md link was flagged as "File
  not found anywhere" and failing CI.

All three checks pass locally (npm run format:check / lint:md /
docs:validate-links).
