`make fmt` now runs prettier over the Markdown files after the Go formatters, and `make fmt-check` fails when prettier would change one. `package.json`, `yarn.lock`, `.prettierrc` and `.prettierignore` are the `sneak/prompts` copies at `dd4027b`, except for `"private": true` in `package.json` in place of the licence field. Both scripts find yarn the way that repo's scripts do. `script/bootstrap` installs prettier with `yarn install --frozen-lockfile`. When the yarn those scripts would run is not 1.22.22, it installs yarn through corepack under node 22.17.0: the node on `PATH` if it has that version, otherwise one installed through nvm from a hash-checked archive. `README.md` and `TODO.md` are reformatted once. Model: opus-5-5
