The perf suite had no terminal scenario, so nothing guarded the terminal row cache (#2239) against regressions. The new terminalTui scenario streams a full-screen TUI into the terminal at 10 fps (every row rewritten, only the spinner row changed, the title updated, as agent CLIs do) while typing in an editor, through a hidden action registered only in dev and perf builds. rowsRebuiltPerTuiFrame counts row elements rebuilt per frame independently of MutationObserver batching and fails when no terminal output arrives; budget 3 (about 1.4 with the cache, the screen height without it).

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).
