To upgrade, use hashString() instead: it hashes with MD5, or SHA-256 in FIPS mode. If you need MD5 itself, call crypto.hash('md5', str) from node:crypto, knowing that it throws in FIPS mode.
Motivation
FIPS mode forbids MD5: md5Hash() throws ERR_OSSL_EVP_UNSUPPORTED there. Since #13007, Docusaurus uses hashString(), and md5Hash() was only left as a public export. Removing it prevents plugins and themes from using it and breaking sites that build in FIPS mode.
Test Plan
No code of the monorepo uses md5Hash() anymore. CI: tests, and the Build FIPS workflow.
Revert the SHA-256 switch: Docusaurus keeps MD5 and its outputs,
and only falls back to SHA-256 in FIPS mode.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Workbox hardcodes MD5 to hash the precached files. In FIPS mode, it
doesn't fail: it only warns and precaches nothing.
The PWA plugin now globs and hashes the files itself with hashString(),
which keeps MD5 and only falls back to SHA-256 when MD5 is not available.
It still applies the Workbox manifest options. globFollow and
templatedURLs are not supported anymore.
Also fixes the user globPatterns being ignored.

Keeps the change non-breaking: instead of rejecting the Workbox options
our file hashing doesn't support, let Workbox handle them, with MD5.

Explanation
The title "break(utils): remove the md5Hash export" matches the main change. The PR removes the md5Hash() function and its export from @docusaurus/utils (packages/docusaurus-utils/src/hashUtils.ts and index.ts). The title names the removed export and the affected package, and the "break" prefix signals the API-breaking nature of the change.

Restore the md5Hash export or treat its removal as a breaking change.
@docusaurus/utils uses src/index.ts as its entry point ("main": "./lib/index.js"). Its exports are public API, even when the monorepo does not use them. Plugins, themes, and sites outside the monorepo can import md5Hash. After this removal, TypeScript builds that import it fail. JavaScript callers receive undefined for that named import.
This PR does not present the removal as a breaking change. Repository guidance requires breaking changes to be discussed before implementation and to use the breaking-change template (CONTRIBUTING.md:227-242). Remove the export only after an explicit maintainer decision, in a breaking release.
To keep this change compatible, restore the export. Its FIPS behavior stays unchanged.
