User policy 2026-07-22: doc examples for the polyglot bin utilities show
the .cmd extension (bin/punk-runtime.cmd ...) - extensionless windows
invocation resolves the .ps1 twin, which is ExecutionPolicy-gated and
runs under the invoking powershell edition, while .cmd always executes
via the wrap-pinned tested path. The same .cmd file runs on unix shells
unmodified, so one form serves all platforms with path-separator style
as the only remaining per-platform difference. Sweep confirmed no
existing user-facing guidance contradicts (none exists yet).
