Stop publishing the repo as a plugin marketplace, and refresh the run skill

Three small things.

Removed `.claude-plugin/marketplace.json`. It is the file `/plugin
marketplace add` reads, so without it this repo no longer offers itself as a
marketplace — which is the odd part of an Angular app carrying one. The
caveman plugin's own files stay, so it can be listed from a marketplace of its
own later; only the listing is gone.

That left four documents asserting an install path that no longer exists,
including a README section handing out `/plugin marketplace add` and
`/plugin install` commands that would now fail. All four now say what is
actually true. `.junie/plans/nasa-star-map.md` still describes the repo as
containing only a marketplace, and is left alone: it records what was here
before the app was written, and is not a claim about the present.

The run skill's numbers had drifted a release behind — 496 tests in 28 files
against a real 527 in 31, and a build timed at 9s that now takes 12. Measured
rather than guessed. The pinned Playwright version it names was correct.

It also gains the Pages build, which is not a plain `npm run build`: the base
href and the 404.html copy are both required for a project site, and the
artifact root is `dist/star-map/browser` rather than its parent. Plus the
matching gotcha, since a Pages build served at `/` looks broken in a way that
tells you nothing about whether it would work.

+## Build for GitHub Pages
+
+`.github/workflows/pages.yml` publishes the app on a push to `main`. To reproduce what it builds:
+
+```bash
+export PATH=/opt/node/bin:$PATH
+npm run build -- --base-href "/star-map/"
+cp dist/star-map/browser/index.html dist/star-map/browser/404.html
+```
+
+Two things differ from a plain `npm run build`, and both exist because a project site is served
+from a subdirectory rather than a domain root:
+
+- **`--base-href`.** `DataLoaderService` fetches its catalogues with relative URLs
+  (`assets/data/stars.bin`), which resolve against `<base>` rather than the current path. Get it
+  wrong and a deep link asks for `/body/assets/data/stars.bin`. The workflow derives it from the
+  repository name so a rename cannot strand it.
+- **`404.html`.** Pages has no rewrite rules, so `/body/mars` has no file behind it. Serving the
+  app as the 404 body lets the router render the route. The response stays HTTP 404.
+
+The uploaded artifact is `dist/star-map/browser`, **not** `dist/star-map` — the parent also holds
+`3rdpartylicenses.txt` and `prerendered-routes.json`, which are not part of the site.
