Widens tsconfig include to nested component TS

Extends the include glob so nested component sources (alpha/,
beta/, open_project/) are matched, and excludes generated .d.ts
files that would otherwise conflict with their sources.

Fixes the Vite dev server in the demo app: its per-file tsconfig
resolution honours include patterns, so unmatched files were
transformed without experimentalDecorators. Catalyst @controller
decorators then reached the browser untransformed, aborting the
whole JS module graph - no custom elements were registered and
ActionMenu overlays rendered as static in-flow content.
