This function: - instantiates `cls(config)` on the meta device - scans `named_modules()` for candidate modules - optionally pre-filters them with `target_modules_patterns` - uses `is_fusable(...)` as the final structural check - builds the class-level patch mapping used by monkey patching Results are cached per `(fusion_name, cls)` to avoid repeated meta-initialization. This matches the current class-level fusion behavior, where one compatible module class maps to one fused replacement class. metaN|)r setdefaultrRr9setrrecompilejoin named_modulesrsearchr$addr(r) rjr)rkrlcachemodel seen_classes patch_mappingtarget_module_pattern module_namer module_clss r_discover_fusable_modulesrs( $ . .{B ? ?E e||Sz f  F 55LM>B>Zd 388D899:::`d %2244 O O V&\\  % %  ,1F1M1Mk1Z1Z1b v&&  $$$-1-B-B:-N-N j)**E#J s AAAc pt||||}|s4t||jdSt |dt |drt |jdstd|jd|jj }| |}t|}|Zd |D}|D]F} t| j } || } | td |d |d | d G||z}t||ddS)aRegister one fusion family for `cls`.
