refactor(async): migrate from blocking HTTP to async/await with tokio

Replace reqwest::blocking with async reqwest across the entire codebase.
All command execute functions, registry API calls (packagist, downloader,
resolver, lockfile), and the main entry point now use async/await with
the tokio runtime. The pubgrub resolver runs on spawn_blocking since its
DependencyProvider trait is synchronous, using Handle::block_on for
async I/O within that context.
