Summary

• Fix path-alias resolution in monorepos: a paths-less root tsconfig.json was short-circuiting alias discovery, silently misclassifying every ~//#/-style import as external across the whole repo instead of resolving it against the actual per-package tsconfig.json
• Track barrel re-exports (export * from, export { X } from, export type { X } from) as dependency facts. Previously these emitted zero facts, making anything only reachable through an index.ts barrel look unused
• Detect plain JavaScript projects (Vue/React/Svelte/Next/Nuxt without TypeScript).

Test plan

• New unit tests: nested monorepo alias resolution, sibling packages with conflicting alias targets, barrel re-export tagging, plain-JS framework detection (positive + negative case)
• Full existing test suite passes, zero regressions
• Verified end-to-end against 4 real repos.
