Subject: [PATCH 1/2] Drop PHP 8.1 support

PHP 8.1 reached end of life. Bump minimum to 8.2, remove 8.1 from
CI matrix, and update lowest-deps validation to run on 8.2.
Closes #790.

Subject: [PATCH 2/2] Cache runtime binaries to avoid GitHub API rate limits

The dload binary downloader uses GitHub API to find and download
release assets for RoadRunner, Temporal CLI, and Temporal test server.
When many CI jobs run concurrently, the 5000 req/hr rate limit is
exhausted causing widespread failures. Cache the extracted binaries
keyed on the dload.xml configuration hash.
