Reformat Code only asked the language server for formatting, so files whose server has no formatting capability (Markdown with marksman, and others depending on the server) could not be formatted.
Languages can now declare an external formatter. Prettier is the first: a managed tool installed on demand, or the project's own node_modules/prettier, an explicit path, or PATH. It runs on the backend copy of the document with the file's path so Prettier resolves the project's config, overrides and ignore files, and its result is applied as one undoable edit. Language servers that format a file keep doing so unless Prettier is preferred in Settings › Languages › Prettier; formatting on save is opt-in. Parsers without range support format the whole file and say so.
Errors carry structured tool data, so a missing Prettier reuses the shared install prompt and Prettier diagnostics or timeouts show as non-sticky notifications.
Fixes#639
HTML files in Angular projects were highlighted as plain HTML. Languages can now declare framework UI modes with root markers (angular.json, node_modules/@angular/core); files under such a root get the framework's editor mode, re-detected when a marker appears or disappears, and the root-marker lookup is shared with language server roots. The Angular Template mode (vendored @codemirror/lang-angular, MIT) adds @if/@for/@switch/@defer/@let blocks, key and animation binding names, and colours {{ }} delimiters.
Lazily loaded editor modes are now loaded before a document's first editor opens, so a file never renders as plain text first (this also left Angular templates uncoloured).

ngserver (@angular/language-server) runs next to vtsls and the HTML server in Angular projects, bringing completion, hover, definition, diagnostics, references and rename to external and inline component templates. A language server can now require a root marker (require-root-marker), so the Angular server only serves files below angular.json or node_modules/@angular/core and never hides the typescript-language-server fallback elsewhere. Attached servers keep definition order, and rename merges the edits of every server that accepts the position. Installable from the tools registry via npm.
