v0.1.2-Support OpenSpec OPSX Detection

Bug Fixes

• Support new OpenSpec OPSX detection via openspec/config.yaml (#4)
• Maintain backward compatibility with legacy openspec/AGENTS.md projects

What Changed

OpenSpec has migrated to OPSX which uses openspec/config.yaml instead of AGENTS.md for project detection. This release adds support for the new format while maintaining backward compatibility with legacy projects.

Thanks to @Aditeya for reporting this issue!
