- Add Homebrew tap (cmnspore/homebrew-tap) with auto-updated formula so macOS and Linux users can install via 'brew install cmnspore/tap/afhttp'
- Add Scoop bucket (cmnspore/scoop-bucket) with auto-updated manifest so Windows users can install via 'scoop install afhttp'
- Update README Install section to document all three installation methods: Homebrew for macOS/Linux, Scoop for Windows, and cargo install for any platform
- Fix BSD sed compatibility bug in release script — replace GNU-only \+ quantifier with \* so the version check works on macOS without GNU coreutils
