import-integrity-lint

Use when ESLint or Oxlint reports a violation from an `import-integrity/` rule, with messages like "must be imported in another file", "must be imported by non-test files", "does not point to a valid first party export", "is not listed in package.json", "Imports/reexports cannot form a cycle", "Test code should not be imported in production code", "Entry point exports should be not imported", or "Default import alias must not have the same name as a named export". Explains the correct fix for each rule, which obvious fixes are wrong, and when a violation needs a human decision instead of a code change.
