📝 Walkthrough

Walkthrough

GoReleaser configuration updated to remove version numbers from archive filenames, and installation documentation expanded with explicit per-platform binary download instructions for Linux and macOS, replacing generic installation guidance.

Changes

Cohort / File(s)	Summary
Build Configuration .goreleaser.yaml	Simplified archive name_template by removing {{ .Version }} token, changing generated artifact names from blogwatcher-cli_VERSION_OS_ARCH to blogwatcher-cli_OS_ARCH.
Installation Documentation skills/SKILL.md	Replaced generic "Binaries" installation link with explicit platform-specific download commands for Linux (amd64, arm64) and macOS (Apple Silicon, Intel), each extracting the binary to /usr/local/bin.

Poem

🐰 Hops excitedly

No versions in the archive names so neat,
Just OS and arch, the naming's complete!
Instructions now crystal, for each platform clear,
Linux and macOS binaries without fear. ✨
