Build: Remove patch-package

[manzoorwanijk]

What?

Follow up to #83847 and #83132

Removes patch-package from the root dev dependencies and the postinstall script, along with the empty patches/ directory.

Why?

The last patch was removed in #83132, so patch-package has had nothing to apply. Since #83847 switched to install-strategy=linked, it would not work anyway: it patches the hoisted node_modules/<pkg> path, which no longer holds the real package.

How?

• Drop the dependency and the patch-package && prefix from postinstall in package.json.
• Delete patches/README.md.
• Drop patches/** from the npm cache key in .github/setup-npm/action.yml and the stale comment in .github/setup-node/action.yml.
• Lockfile regenerated with npm 11.

The patch-package example in the iframe migration guide stays, since it targets third-party block authors.

Testing Instructions

1. npm install completes and postinstall only runs agents:setup.
2. CI passes.

Nice! 🎉 I've long awaited this day 😄

Hopefully we can get rid of the postinstall altogether some day soon. With Claude recently adding support for AGENTS.md, one can hope they'll soon also add support for .agents/skills, which is the root motivation behind the remaining postinstall task.
