Pre-built binaries for PIE installation

[derrickschoen]

Problem

Every install method (PIE, PECL, manual) compiles the Rust FFI library from source. This takes 8-10 minutes and requires a Rust toolchain on the target machine.

Proposal

Ship pre-compiled valkey_glide.so binaries as GitHub Release assets so pie install downloads a binary in seconds instead of compiling.

PIE supports this via download-url-method: ["pre-packaged-binary", "composer-default"] in composer.json and a naming convention for release assets:

php_valkey_glide-{ver}_php{major.minor}-{arch}-{os}-{libc}{-zts}.zip

What's needed

1. A release-binaries.yml workflow triggered on release: published
2. download-url-method added to composer.json php-ext section

Suggested matrix (24 binaries)

Platform	PHP	Thread safety
Linux glibc x86_64	8.2, 8.3, 8.4, 8.5	NTS, ZTS
Linux glibc aarch64	8.2, 8.3, 8.4, 8.5	NTS, ZTS
macOS aarch64	8.2, 8.3, 8.4, 8.5	NTS, ZTS

Pipeline design

The Rust FFI static library (libglide_ffi.a) is PHP-version-independent. Build it once per (OS, arch), then compile only the PHP C wrapper per combination. This avoids rebuilding Rust 24 times.

• Stage 1: 3 jobs (~3 min each) — build libglide_ffi.a
• Stage 2: 24 jobs (~1 min each) — compile C wrapper, verify, package ZIP
• Stage 3: 1 job — attach ZIPs to release
