unused-file: directory barrels (index.ts) reached via directory-path imports flagged as unused

[dayrell19]

Version: react-doctor 0.9.12

unused-file flags directory barrel files (index.ts re-exports) that are actually reachable through directory-path imports.

Repro shape:

src/features/foo/index.ts   // export * from "./foo-list"; export * from "./foo-card"
src/screens/bar.tsx         // import { FooList } from "@/features/foo"

The barrel is imported via the directory specifier (@/features/foo → resolved by TS/bundler to foo/index.ts), but dead-code analysis reports src/features/foo/index.ts as an unused file. Deleting it breaks the build, so the finding is a false positive.

Likely the resolver isn't applying Node/TS directory-index resolution (or the project's paths aliases) when building the import graph for dead-code analysis. We confirmed this on a Next.js app with @/* path alias in tsconfig.json.
