Build bundled Phaser projects with their own toolchain

The step assumed one project shape: plain sources concatenated with cat
and Phaser pulled from a CDN. trickster-tiles is the other shape — Vite
plus TypeScript, built with `tsc && vite build` — so `cat src/*.js`
found nothing to bundle and the build failed. The earlier guard on the
syntax check fixed only the first symptom of that mismatch.

A project with a build script now runs npm ci && npm run build and is
packaged from its own dist/, which already contains index.html and the
hashed assets. Plain projects keep the existing path untouched.

The bundler's base has to be relative, since games are served out of
/file/<name>-<version>/; the step fails loudly if the build leaves no
dist/index.html rather than shipping an empty zip.

Verified in the phaser-builder image against trickster-tiles: a 344 kB
package with index.html at the root and ./assets/ references.
