Adding Bestie features to a package

bestie add-feature applies a named slice of the BestieTemplate copier template to an existing package: only the feature's files are written, everything else is left untouched. Requires only uv on the PATH.

bestie in the commands below stands for this full invocation:

uvx --from bestie-template bestie

(The --from is needed because the package is bestie-template and its command is bestie.) Inline the full invocation in every command — do not rely on a shell alias or variable, which won't survive when each command runs in a fresh shell.
