refactor: Change hero action syntax to verb.noun

- Change action name format from `obj.verb` to `verb.obj`
- Update decoder to look for `define.obj` or `configure.obj`
- Modify encoder export to use the new `define.obj` prefix
- Update all test constants and scripts to the new syntax
- Make Remark struct public for test visibility
