eslint-plugin-cflint

ESLint plugin providing two custom CloudFlare-specific linting rules: `no-substr` (prevents use of `String.prototype.substr`, considered legacy) and `no-this-assignment` (prevents assigning `this` to a variable). Current stable version is 1.0.0, initially released with no further updates. It requires ESLint as a peer dependency. Differentiators: lightweight and focused exclusively on patterns flagged internally by CloudFlare; minimal setup and no extra dependencies. Release cadence: single release, no maintenance indicated.
