refactor(detection): use catalog version_args instead of hardcoded special cases

- Add version_args field to catalog/*.json for custom version detection
- Implement ToolCatalog.has_tool() and get_raw_data() methods
- Pass version_args from catalog to detection functions
- Remove hardcoded curlie version detection special case
- Add version_args: ["version"] to catalog/curlie.json

This makes version detection more maintainable by moving tool-specific
detection logic from Python code to catalog metadata.
