Closes #54. The existing `design.md` bin entry produces a `node_modules/.bin/design.md` shim file on Windows. Because the basename ends in `.md`, Windows command resolution short-circuits to the Markdown file association before iterating PATHEXT, so PowerShell opens the shim in the user's Markdown editor (VS Code by default) instead of executing it. Add a `designmd` alias bin that resolves to the same entrypoint. The dot-free name lets the npm CMD/PowerShell shims resolve cleanly via PATHEXT on Windows while leaving the original `design.md` bin in place for posix users and existing scripts. * `packages/cli/package.json`: add the alias to the bin map. * `README.md`: add a "Windows tip" callout under CLI Installation explaining when to reach for the alias. * `packages/cli/scripts/check-package.ts`: new check #5c verifies the bin map exposes at least one dot-free alias so future package edits don't silently regress this. Pre-existing failure #20 (`CLI spec command failed to load spec.md`) reproduces on `main@8ecd464` with my changes stashed (23 pass / 1 fail); adding 5c yields 24 pass / 1 fail, with no other deltas.
