xint-missing-internal-modules-need-shimming
xint may reference internal modules (e.g., spinner.ts) that are absent or not bundled in distributed releases. When installing a new xint version, test immediately with bun run xint.ts --help to surface any missing module errors before production use. Missing modules require manual shimming (create stub files) or waiting for the upstream fix — do not assume a clean bun install means all modules are present.
