jsr-exports-lint

A linting tool for validating the `exports` field in JSR's `jsr.json` manifest files, designed to be used as a build hook in `tsdown` or `unbuild`. Current stable version is 0.4.2. Released under MIT license with active development. Key differentiator: unlike `publint` which lints npm `package.json` exports, this tool specifically targets JSR's `jsr.json` exports, making it essential for library authors distributing via both npm and JSR. It fully supports TypeScript and requires Node >= 20. The lint runs after the build is done, checking that all exported entries match the actual built files.
