- Add call_cfunc_metamethod_1/2/3 for 1/2/3 argument CFunction calls - Avoid Vec allocation in metamethod calls by using fixed-size paths - Optimize call_function_internal: only init registers beyond args - Remove stack cleanup on normal return (let GC handle stale refs) - Update table_get_with_meta/table_set_with_meta to use fast paths - Update userdata_get and string_get with CFunction fast paths Performance improvements: - __index (table): +22% (18M -> 22M ops/sec) - __newindex: +33% (4.5M -> 6M ops/sec) - __len: +10% (4.6M -> 5.1M ops/sec) - ipairs: +150% (10K -> 25K iters/sec) - pairs on hash: approaches native Lua performance
