Align Python VFS resources with the wire format

### Feature Summary

The Python VFS resource enum does not match the lowercase resource suffixes written by Scala. Scala emits `runtimestatistics` and `consolemessages`, while Python stores `runtimeStatistics` and `consoleMessages`.

Before: Scala emits a lowercase suffix, Python normalizes it, and enum lookup fails.

After: the Python enum uses the shared lowercase wire values and lookup succeeds.

Reproduction on main:

```text
VFSResourceType("runtimestatistics") raises ValueError
VFSResourceType("consolemessages") raises ValueError
```

### Proposed Solution or Design

Align the two Python enum values with the Scala wire format. Keep the decoder normalization and test literal Scala-produced suffixes.
