- lib/Channel.bux: add Channel_Recv_Ok<T> for use in for-in desugaring - hir_lower.bux: Channel for-in desugars to while+recv_ok pattern - c_backend.bux: emit 'break;' / 'continue;' with semicolon, fix missing semicolon when break/continue inside if-block - bootstrap/hir_lower.nim: skip generic methods in vtable generation to avoid referencing non-existent monomorphized C functions
