 #!CommitTicketReference repository="" revision="61611"
 Code Editor: Switch from Esprima to Espree for JavaScript linting in
 CodeMirror.

 Esprima is no longer maintained, and it does not support the latest
 JavaScript features in ES11, as Espree does.

 - **New Linter Integration:** Introduces
 `src/js/_enqueues/vendor/codemirror/javascript-lint.js` using `espree` for
 parsing and error reporting, replacing the dependency on `jshint` and
 `esprima` scripts.
 - **Script Modules:** Registers `espree` as a script module and leverages
 the `module_dependencies` argument in `wp_register_script()` to ensure
 `espree` is available as a dynamic import.
 - **Editor Settings:** Updates `wp_get_code_editor_settings()` to use ES11
 (ECMAScript 2020) defaults and synchronizes JSHint settings from
 `.jshintrc` for compatibility.
 - **Editable Extensions:** Adds `.mjs` to the list of editable file
 extensions for plugins and themes.
 - **Deprecations:** Marks `esprima` and `jshint` script handles as
 deprecated.
 - **Build Tools:** Updates Webpack configuration to bundle `espree` as a
 module and use the new local `javascript-lint.js`.
