v0.1.1

Added

• Homebrew (brew install candril/tap/lane) and Nix (nix run github:candril/lane) via
  candril/homebrew-tap, alongside the curl installer.
  All three install the release binary, verified against SHA256SUMS.
• The installer, build script and release workflow shared with the sibling tools; a released
  binary reports its tag, and the release writes release.json for the Nix flake.

Changed

• The README and docs site carry the shared spec-driven notice, the same install section as
  the sibling tools, and a footer linking them.
• Demo gif paced by caption, with the moved card ringed; docs screenshots with solid scrollbars.
