feat: create proper Homebrew bottle archives in releases

Update release workflow to generate proper Homebrew bottle archives
alongside raw binaries for maximum compatibility.

Changes:
- Create bottles with correct naming: wt--VERSION.PLATFORM.bottle.tar.gz
  - arm64_sonoma (macOS Apple Silicon)
  - ventura (macOS Intel)
  - x86_64_linux (Linux x86_64)
  - aarch64_linux (Linux ARM64)
- Create proper bottle structure: wt/VERSION/bin/wt
- Separate Windows build job (no Homebrew on Windows)
- Upload both bottles and raw binaries to releases
- Generate checksums for all artifacts

Bottles are now compatible with Homebrew's bottle DSL.
Raw binaries still available for non-Homebrew users.
