fix: cargo upstream proxy + mirror UX improvements (#107)

Browse Source 
- Add CargoConfig with upstream proxy to crates.io (NORA_CARGO_PROXY)
- Cargo download/metadata: try local storage first, fetch from upstream on miss, cache in background
- Detect yarn.lock in npm subcommand and suggest correct command
- Add pip transitive dependency warning for air-gapped installs
- Improve mirror error messages with HTTP status codes
