Reorder the added component and stylesheet tests so the dotenv tests on main can merge without overlapping insertions. Preserve all highlighting behavior and existing test assertions.

66-66: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAssert the Svelte language name in the mapping test.
Counter.sveltecurrently has only a non-null assertion. The syntax test checks generic script colors, so it does not distinguishsvelte()from another component language. Add it to the exact language-name table so a replacement withvue()fails the test.Suggested fix

What changed
languageForPathnow maps.vue,.svelte,.scss,.sassand.lessto CodeMirror languages, so the file editor and the diff view color these files instead of showing plain text. Each language is loaded lazily withimport(), like the existing ones..vue@codemirror/lang-vue→vue().svelte@replit/codemirror-lang-svelte→svelte().scss/.sass@codemirror/lang-sass→sass()/sass({ indented: true }).less@codemirror/lang-less→less()Tests were added to
editorLanguage.test.ts(each language is resolved) andsyntaxTokens.test.ts(script blocks in Vue/Svelte and comments in SCSS/Less get the expected colors).Why
Closes #695. Single-file components and stylesheets in Vue/Svelte projects showed up without colors in the editor and in diffs.
UI
No layout changes. These file types now get syntax colors.
Checklist
npm run check:web(no Rust changes). All tests pass exceptagentAppMemory.test.ts > lets the Mono add, pause, try and remove its habits. That test also fails onmainon my machine because it depends on the system locale (it expects9:00 AM, my 24-hour locale gives9:00).Summary by CodeRabbit
