Breaking changes

Updated the server to Angular Language Server 22, which requires Node.js 22.22.3+, 24.15.0+ or 26+.
If you use your own Node.js installation, make sure that it matches these versions.
The server now uses TypeScript 6. The Angular 22 compiler reports some new template diagnostics
(for example nullishCoalescingNotNullable and optionalChainNotNullable) that might appear in existing projects.
Use the angular.suppressAngularDiagnosticCodes setting to hide specific diagnostics.
The angular.* settings were previously not passed to the server and had no effect. They are now applied, which
means that:
- angular.suggest.includeAutomaticOptionalChainCompletions and angular.suggest.includeCompletionsWithSnippetText
  are now enabled by default.
- The server no longer writes a log file unless angular.log is set to a value other than off.
  Most of those settings require restarting the server after changing them.

Features

Added settings for Angular template inlay hints (angular.inlayHints.*) and document symbols
(angular.documentSymbols.*).
Added the angular.server.useClientSideFileWatcher setting that delegates file watching to Sublime Text.
Requires a file watcher package, for example LSP-file-watcher-rust.
Prompt to enable strictTemplates when it is disabled in the project (can be turned off with the
angular.enable-strict-mode-prompt setting).
Show "initializing" in the status bar while the server loads a project.
