Subject: [PATCH 1/2] feat(pigz): add madler/pigz llar formula

Add build formula for pigz (parallel implementation of gzip).
- Uses plain Makefile build system with zlib dependency
- Installs pigz and unpigz binaries to bin/
- Uses semver version comparator for v2.x tags

Subject: [PATCH 2/2] refactor(pigz): use autotools instead of exec make

Replace manual CFLAGS/LIBS injection via exec make with autotools.new()
and a.use() to properly inject zlib dependency paths through CPPFLAGS/LDFLAGS.
