ci: build + test pipeline (GitHub Actions)

One job on ubuntu-24.04 (libuv >= 1.45 for TrueAsync): build the
true-async/php-src fork (cached by its branch SHA), build the vendored
Rust core c-bridge (cargo cache), build the extension, start the Temporal
dev server in Docker, run the full phpt suite (offline + live), then check
out the SDK fork and run its truasync integration tests over the freshly
built extension.
