fix: Make resolver quiet for dependency chains, reduce timeouts

- Only show resolver debug output for first package lookup
- Hide verbose output for dependency resolution chains
- Reduce HTTP timeout from 30s to 10s for faster failure
- Add ExpectContinueTimeout for better HTTP performance
- Fix neovim install showing endless resolver output
