feat: include headers from portable deps for native gem compilation

[jdx]

Summary

When using precompiled Ruby binaries, gems with native extensions (like openssl, psych, ffi) fail to compile because headers are missing from the tarball.

This change:

1. Copies headers from portable dependencies (openssl, libyaml, libffi, zlib, libxcrypt) into the Ruby tarball's include/ directory during packaging
2. Updates rbconfig.rb to include -I#{prefix}/include in CPPFLAGS and -L#{prefix}/lib in LDFLAGS so mkmf can find the headers when building native extensions

Background

Reported in mise discussion: jdx/mise#7268 (comment)

Users on macOS with precompiled Ruby were unable to update gems because native extensions couldn't find necessary headers:

• cannot find openssl/ssl.h
• cannot find yaml.h

Changes

• cmd/jdx-package.rb: Added copy_portable_headers method that copies headers from installed portable dependencies into the extracted Ruby directory before re-tarballing
• Abstract/jdx-ruby.rb: Added inreplace block to patch rbconfig.rb with include/lib paths

Test plan

• CI builds pass on macOS and Linux
• Verify headers are present in extracted tarball: tar -tzf ruby-3.4.1.macos.tar.gz | grep include
• Test native gem installation: gem install openssl psych

Note

Bundles headers/static libs/pkg-config from portable deps into Ruby formulas and updates CI to build on PRs with a required status check.

• Portable Ruby formulas (Abstract/jdx-ruby*.rb):
  • Copy portable dependency assets for native gem builds via copy_portable_deps_for_native_gems (headers, static libs, pkg-config); set portable_deps (adds libffi, zlib, libxcrypt on Linux).
  • Remove shipping libxcrypt's libcrypt.a directly.
  • Tests: set ENV["PKG_CONFIG_PATH"] = "lib/pkgconfig"; install native gems (openssl, psych) to validate headers; keep existing byebug test.
  • Update bundled bootsnap gem version in jdx-ruby-34.rb and Abstract/jdx-ruby.rb.
• Portable mixin (Abstract/portable-formula.rb):
  • Add copy_portable_deps_for_native_gems helper to copy headers, *.a, and patch .pc files with relocatable prefix.
• CI (.github/workflows/tests.yml):
  • Add build job for PRs using ./.github/workflows/build.yml with formula: jdx-ruby@3.4.1.
  • Add conclusion job to surface a single required status check.

Bug: Missing native gem tests for Ruby 3.2 and 3.3

The PKG_CONFIG_PATH environment variable is set in tests for jdx-ruby-32.rb and jdx-ruby-33.rb, but unlike jdx-ruby.rb and jdx-ruby-34.rb, these files don't include the gem install openssl and gem install psych tests that verify the new header-copying feature works. The feature is implemented identically across all versions, but only tested on Ruby 3.4 and HEAD. If there's a version-specific issue with native gem compilation on Ruby 3.2 or 3.3, the tests wouldn't catch it.
