Replaced SystemJS transpiler: 'ts' / plugin-typescript with custom loaders (demo-ts-loader, demo-vue-loader, shared via demo-ts-shared) that transpile on demand through the official typescript API.
Why
plugin-typescript did not give enough control over compiler options needed for TypeScript 6 (e.g. ignoreDeprecations: '6.0', moduleResolution: Bundler). The new loaders own the transpile step and accept per-file typescriptOptions from SystemJS meta (e.g. jsx: 'react' for .tsx).
What changed
All framework configs use transpiler: false with explicit loader rules
TypeScript is loaded lazily (no <script src="typescript.js"> in demo HTML)
Per-framework loaders consolidated into a single demo-ts-loader
