* feat(recomp): Reduce recompiler output memory usage Stream output generation, add low-memory config controls, and avoid pathological indirect-jump switch expansion in generated C++. Low-memory mode now avoids retaining per-instruction disassembly strings while still emitting asm comments during output generation. Output workers are bounded/configurable, combined output is streamed, and decoded buffers are released after generation. Also document the new output memory settings. * fix(recomp): added tests for unregistered JR/JALR, updated fallback logic to cover JR/JALR, moved Rabbitizer formatting into R5900Decoder
