Pull Request Overview
This PR refactors Python object detection for Valgrind to find all installed Python versions instead of relying on a single system Python. The change replaces the previous approach that used Python's sysconfig module with a more comprehensive method that searches for Python installations through both uv (Python version manager) and system paths.
- Replaces single Python detection with comprehensive multi-version discovery
- Adds support for uv-managed Python installations alongside system Python
- Implements filesystem-based library discovery instead of relying on Python's sysconfig

Using unwrap_or_default() on JSON parsing will silently return an empty JSON value for invalid JSON, which could mask parsing errors. Consider using proper error handling with context() to provide meaningful error messages when JSON parsing fails.

Using which command is not portable across all systems (not available on Windows). Consider using a more portable approach or add platform-specific handling for cross-platform compatibility.
