feat(site): read every satellite's count from summary.json

The homepage counted cpu-engineering-samples by downloading its whole
catalog and reading `.length`. game-catalog is ~1M records, so that had to
change before games could count at all: satellites now publish
`summary.json` and the page reads `count` from it.

The satellite list is data rather than three hard-coded places, so the next
split is one line. `/v1/games/index.json` keeps a small pointer to the new
home instead of 404-ing; its .gitignore exception (the 125MB list file) is
no longer needed.
