Håkon Hægland 85344a3998 Auto-detect installed Python versions at runtime ...

When no --python-versions is specified at
runtime, auto-detect which Python versions are actually installed in the
container instead of defaulting to all versions from python_versions.json.

This resolves the issue where:
1. Building with --python-versions=3.12 installs only Python 3.12
2. Running without --python-versions would try to test all versions from JSON
3. Tests would fail for non-installed versions (3.8, 3.9, 3.10, 3.11, 3.13)

Now the runtime logic:
1. Uses `pyenv versions --bare` to detect installed versions
2. Maps full versions (3.12.9) to short versions (3.12)
3. Uses detected versions as default for testing
4. Falls back to JSON versions if detection fails

Example behavior:
- Build: --python-versions=3.12 (installs only 3.12.9)
- Runtime: auto-detects 3.12, tests only that version
- Explicit: --python-versions=3.11,3.12 still works as before
