Bump Jest to 30.4.2 and pin @babel/core to 7.29.6

[Copilot]

Should address this security finding: https://github.com/github/markdownlint-github/security/dependabot/47
🤞 - we want babel/core 7.29.6

Updates the repository’s Jest toolchain to 30.4.2, pins the transitive Babel core dependency to 7.29.6, and refreshes the npm lockfile to match the resolved dependency graph. This keeps the test runner version current without changing the package’s runtime surface.

• Dependency update

  • Raises the jest devDependency from ^30.0.3 to ^30.4.2 in package.json.

• Transitive dependency pin

  • Adds an npm overrides entry for @babel/core at 7.29.6 so the Jest toolchain resolves the requested Babel core version consistently.

• Lockfile refresh

  • Regenerates package-lock.json via npm install so the checked-in lockfile matches the updated Jest version, the @babel/core override, and their transitive resolutions.

@copilot i noticed babel/core didn't get updated in package-lock.json - i'd like it to be updated to 7.29.6, how can we make that happen? which npm package can we upgrade to make babel/core go up to 7.29.6?

There isn’t a separate top-level package we can upgrade to land exactly on @babel/core@7.29.6 here — the existing Jest packages already allow that range, and a plain refresh now resolves to 7.29.7. I addressed it in 9922b24 by adding an npm overrides entry for @babel/core: 7.29.6 and refreshing the lockfile, so package-lock.json now resolves to 7.29.6 consistently.
