Repositories copy package.json to get prettier, and with "license": "MIT"
each of them declared MIT whatever its own licence is. "private": true
keeps yarn from printing "No license field" and makes no licence claim.
This repository's LICENSE and README License section are unchanged.
Model: opus-5-5
`package.json` now carries `"license": "MIT"`, matching `LICENSE`. Without it yarn printed `warning package.json: No license field` and `warning No license field` each time `script/bootstrap` ran inside the Docker phases of `make check`. No other yarn warning appears in the bootstrap output.

Add .gitignore, LICENSE (MIT), Makefile, Dockerfile, .dockerignore,
and pin prettier via yarn lockfile for integrity-checked markdown
formatting. Update REPO_POLICIES.md self-reference to point to this
repo. Format markdown files with prettier.
