feat: generalize AGENTS.md for any AI coding agent
- Rename title from CLAUDE.md to AGENTS.md - Generalize intro text to be agent-agnostic - Remove maintainer-specific Notion workspace section - Update README.md references to AGENTS.md - Add UE path detection scripts (Content/Scripts/) - Extend ue_python_finder.py with find_ue_source() function Developers can now run detect-ue-path.bat/.sh to auto-detect their UE installation and update AGENTS.md.
