6.1 has no prepareMthHashSet and no id-switch: CMC_*_Runner::run takes the method
*name* (CXString) and dispatches via a `CXString(tmp,"name"); equalsIgnoreCase(name)`
chain. extract_methods now falls back (only when the hashset pass finds nothing) to
scanning run() for that pattern, recovering the names (no numeric ids).
6.1 now yields 186 methods (Animo: show/hide/play/setFPS/...); dispatch stays 0 since
the string chain isn't a jump table. 7.1/8.x untouched (they have prepareMthHashSet).
Note: 6.1 names are camelCase/lowercase vs 7.1+ UPPERCASE (engine compares case-
insensitively), so a cross-version method diff needs case folding to be clean.
38/38 tests (test_versions updated: 6.1 methods present with id=None).
