v0.1.0 - Initial Release!

Added

• First public release of the metal2vulkan crate and CLI: native Metal AIR / sanitized
  LLVM IR → Vulkan SPIR-V (no LLVM llc on the product path).
• Library entry points for stage-aware translate, optional reflection metadata, and
  function-constant specialization.
• CLI: metal2vulkan <in.air|.ll> <out.spv> --stage …, optional --emit-meta JSON with the
  serde feature, PASS / FALLBACK reporting, and FALLBACK repro bundles under
  $TMPDIR/metal2vulkan-repros (override with METAL2VULKAN_REPRO_DIR).
• Optional serde feature for serializable ShaderReflection / metadata dumps.
• Consumer docs: architecture overview and reflection binding layout (docs/).

Notes

• The crate is alpha (0.x): public API, CLI flags, and SPIR-V output may still change.
• This package does not ship third-party captured shaders; coverage is synthetic fixtures and
  unit tests only.
