Framework work on codex/mmx6-support that makes Tomba build and play (title screen, 0 dispatch misses) and MMX6 boot through BIOS to its intro. Touches recompiler codegen (code_generator, function_analysis) and runtime CD-ROM/DMA/MDEC/GPU/SIO timing (cdrom, dma, mdec, gpu, psx_cycles, traps, fntrace, debug_server) + headers + runtime.cmake. Milestone snapshot for collapsing onto master. Build dir excluded. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
