Pull request overview

This PR makes the return-type definition for getOsInfo part of the public API surface of the get-os-info package by exporting the relevant TypeScript types from both the implementation module and the package entrypoint.

Changes:

• Export LinuxInfo, DarwinInfo, and OsInfo types from src/get-os-info.ts.
• Re-export those types from src/index.ts via a type-only barrel export.
