// resolution but do not affect the JS bundles:
// 1. Side-effect CSS imports (e.g. `import "./index.css"`) — TypeScript cannot
// resolve a `.css` file as a typed module (InternalResolutionError). The CSS
// import is intentionally kept in the JS so styles auto-load for bundler
// consumers; only the declarations are cleaned.
// 2. The headless re-export of the externalized context module is emitted as a
// relative `./context` import, which is invalid in ESM declarations
// (extensionless). Rewrite it to the package subpath so it resolves under
// node16/nodenext/bundler — matching how the JS bundle externalizes it.
// Run from `build:done` so it processes every format's declarations on disk,
// independent of per-output plugin order (the esm `.d.mts` and cjs `.d.cts` are
// emitted in separate passes).
