feat(redis_binary): Add libc parameter, default to musl for static li… …nking The redis_binary function now accepts a libc parameter ('musl' or 'glibc') to choose between statically-linked and dynamically-linked binaries. Default changed from glibc to musl because: - musl builds are statically linked (no external dependencies) - Works in hermetic build environments like RBE where glibc's dynamic linker (/lib64/ld-linux-x86-64.so.2) is not available - glibc builds fail on RBE with "Failed to create confirmation" because redis-server can't start without the dynamic linker Users who need TLS support (which requires OpenSSL) can explicitly set libc="glibc" to get dynamically-linked binaries.

fix: Remove --strip-components from redis_binary extraction 

feat: Add redis_binary() for pre-built binary downloads 

Add musl/Alpine Linux support with static linking - Add libc parameter to redis_stack() to support both glibc and musl builds - musl builds use static linking with libc malloc (no jemalloc/TLS dependencies) - Share download between glibc and musl variants to avoid duplication - Add redis_stack_musl target for Alpine-compatible binaries - Update README to document musl build requirements and remove manual extraction - Document required dependencies: musl-tools, musl-dev 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
