TypeScript 7 is the native (Go) compiler and does not ship a JS API. Following the upstream recommendation, `typescript` is aliased to `@typescript/typescript6` so tools that use the compiler API (typescript-eslint, ts-jest, ts-node, ts-json-schema-generator, Storybook) keep working, while `@typescript/native` provides the TypeScript 7 `tsc` used for type-checking. - Replace gulp-typescript with the TypeScript 7 `tsc` CLI in gulp tasks - Replace the removed `moduleResolution: node` with `bundler` in src/view - Declare `*.css` modules for side-effect CSS imports - Fix webview event handler types surfaced by the stricter resolution - Update the VS Code build task problem matcher Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: c2c54892-58d8-42e7-940b-8a0e22f9fa6d

Bumps TypeScript to 7.0.2, the native (Go) compiler, which makes type-checking dramatically faster (gulp type-check tasks now take ~0.4s).
TypeScript 7.0 does not ship a JS compiler API, so following the official recommendation we install both side by side:
typescriptis aliased to@typescript/typescript6(6.0.3), so tools that use the compiler API (typescript-eslint, ts-jest, ts-node, ts-json-schema-generator, Storybook) keep working.@typescript/nativeistypescript@7.0.2and provides thetscbinary used for all type-checking (npm run check-types, gulp build/watch).Other changes
gulp-typescript(which uses the TS API) with spawning the TS 7tscCLI; removedgulp-typescriptandansi-colors. Updated the VS Code Build task problem matcher for the new output format.src/view/tsconfig.json:moduleResolution: nodeis removed in TS 7, switched tobundler. This picks up packages'exportstypings and surfaced three incorrect event handler types inRenamingInput.tsxandRAPrettyPrinter.tsx, which are fixed.noUncheckedSideEffectImportsis now on by default, so addeddeclare module "*.css"(and included it in the stories tsconfig) for side-effect CSS imports.Notes for reviewers
.vscode/settings.jsontypescript.tsdkstill resolves to the TS 6 language server. Use the TypeScript 7 VS Code extension for TS 7 in the editor.Validation
