fix: auth response parsing + multi-platform Python wheels

Auth:
- AuthUser subscription fields are integers (0-3), not strings
- Removed stale subscription_level field reference
- Verified against live Nexus API (session established, data returned)

Python SDK:
- Build matrix: Linux + macOS + Windows wheels
- Source distribution (sdist) for pip install from source
- Fixes "no matching distribution" for non-Linux users
