feat(release): package binaries in archives

[Snider]

Summary

Package release binaries in compressed archives for easier distribution.

Changes

• Binary built as core (or core.exe) instead of core-{os}-{arch}
• Unix builds: core-linux-amd64.tar.gz, core-darwin-arm64.tar.gz, etc.
• Windows builds: core-windows-amd64.zip

Why

Prepares for dogfooding - host-uk/build can download and extract the core CLI to replace complex GitHub Actions with simple core build, core release commands.

Summary by CodeRabbit

• Chores
  • Release artifacts are now delivered as compressed archives for improved distribution efficiency. Unix-based platforms receive tar.gz packages while Windows receives zip packages, replacing the previous raw binary format.
  • Build output naming convention has been simplified for better consistency across all target platforms.

📝 Walkthrough

Walkthrough

This pull request modifies the GitHub Actions release workflow to consolidate build output into a single filename format and adds automated archive creation steps. Unix builds are packaged as tar.gz files while Windows builds become zip archives, with original binaries removed after archiving.

Changes

Cohort / File(s)	Summary
GitHub Actions Release Workflow .github/workflows/release.yml	Simplified build output path from per-target naming to dist/core${{ matrix.ext }}. Added conditional archive creation: tar.gz for Unix platforms and zip for Windows, with cleanup of original binaries after packaging.

Poem

🐰 Hop, hop, the bunny cheers,
Archives bundled, tidy spheres!
Tar and zip, they wrap so tight,
Build releases, oh what a sight! 🎉
