feat: precompile nginx binary on release and download during builds

Browse Source 
On release creation, a GitHub Actions workflow compiles a statically-linked
nginx binary and uploads it as a release asset. During builds, the compile
script now attempts to download the precompiled binary before falling back
to source compilation, significantly speeding up cold-cache deploys.
