Brings trac/ in line with the formatting and lint rules from WordPress#734, ahead of that PR, so the same files do not need touching again when it lands and the assets only need deploying once. Retires the jinja2 compatibility shim: its rules now live in wp-trac.css and the templates no longer load the removed script and stylesheet. trac-search.js goes with it, unused since its include was removed in r7275. Builds markup through the DOM rather than by string concatenation in the attachment preview, the reopen notice, the non-gardener type field and the attachment autocomplete, and restores the preserved attribute matches by index so a comment cannot shift the restore queue.

Pull request overview
Modernizes the build and maintenance workflow for wordpress.org/public_html/style/ by migrating from Grunt/JSHint to @wordpress/scripts, regenerating committed build artifacts accordingly, and adding CI checks to prevent drift and enforce lint/format rules for the Style assets.
Changes:
- Replace Grunt/JSHint tooling with
@wordpress/scripts-based build/lint/format commands and updated browser targets. - Introduce a custom webpack config and a Node-based RTL build script, committing regenerated outputs (
wp4-rtl.css,js/navigation.min.js). - Add documentation for the Style and Trac asset workflows plus a dedicated GitHub Actions workflow for lint/format/build-drift checks.

- Swap Grunt/JSHint for @wordpress/scripts (build, lint-js, format), with a webpack config that builds js/navigation.min.js in place and a small bin/build-rtl.js for the RTL stylesheet, keeping the Dashicons arrow swap RTLCSS cannot infer. - Adopt the default WordPress code style (Prettier at a 120 line length) and fix all ESLint errors; convert HTML-building string concatenation to template literals and query building to URLSearchParams. - Update browser targets to @wordpress/browserslist-config, matching the rest of WordPress.org, and drop the vendor prefixes nothing supported needs anymore, along with the Autoprefixer pass and the self-referential wp4.css.map. - Remove trac/trac-search.js, unused since its include was removed in r7275. - Document the directory in README.md, trac/README.md, and AGENTS.md (with a CLAUDE.md wrapper): file inventory, development flow, testing Trac changes via DevTools overrides, and the deploy + scripts_version bump process.
Runs on changes to JS or CSS under wordpress.org/public_html/style/ and fails when the tooling wasn't run: ESLint errors, unformatted files, or committed build output (wp4-rtl.css, js/navigation.min.js) that is out of sync with its source.
Their behavior now lives in wp-trac.js and wp-trac.css; remove the files, their template includes, and their README entries. scripts_version is deliberately untouched: per the documented deploy flow it gets bumped in a follow-up commit once the merged assets are deployed, so the CDN never caches a stale file under the new version.

Adds wp-scripts lint-style (the stock @wordpress/stylelint-config) as npm run lint:css, wired into the CI workflow, and conforms wp4.css and trac/wp-trac.css to it. Prettier ignores *.css, so stylelint owns CSS formatting outright. The fixes are rendering-identical: formatting, notation (::before, bold=700, named colors to hex, quote style), dropped declarations that a later duplicate in the same block already overrode, and generic font-family fallbacks — including 'Open Sans', "sans serif", which quoted the generic keyword into a nonexistent font name. Cascade-affecting rules (selector reordering/merging, renaming the Trac and WP.org markup's own ids and classes, unit conversions) are disabled in .stylelintrc.js. Vendored, generated, and frozen legacy stylesheets are excluded via .stylelintignore; wp4-rtl.css is rebuilt from the conformed wp4.css.

Chrome stores DevTools local overrides with the query string in the file name and only matches that exact name; hand-placed files without it are silently ignored, as are tabs without an open DevTools window.

The command table claimed `npm run format` "formats all source files", which reads as including the stylesheets. It does not: `.prettierignore` excludes `*.css`, so Prettier never touches them. Say what it actually formats, and note why the CSS is left out. The stylesheets are linted, just by Stylelint rather than Prettier, so also document `npm run lint:css` — it was missing from the table even though CI runs it.

Trigger validation when Stylelint exclusions change.
The path filters omit wordpress.org/public_html/style/.stylelintignore. A pull request that changes only this file skips lint, format, build, and generated-file drift checks. Add this path to both event filters. GitHub runs a path-filtered workflow only when a changed path matches an included pattern. (docs.github.com)

Generate the mirrored make-cli Dashicon.
The RTL build contract maps \f345 to \f341, but both selectors retain \f345. RTL make-cli headings and site titles therefore use the unmirrored arrow glyph. Fix the generator or its input handling, then rebuild wp4-rtl.css. Do not edit this generated file directly.
