Claude 7c8298b12e docs: round 7 — remaining Kula wedge is unserviced CD IRQ (libcd CdSync never completes) ...

With the boot fixed, live state during the game's retry loop shows the CDROM
interrupt is raised (i_stat bit2) AND enabled (i_mask bit2) and the CPU takes
exceptions (VBLANK cleared each frame), yet the CDROM bit is never cleared and
the response FIFO never drained (irq_flag=0x03, response_read=0). The game's
libcd CD interrupt handler in the BIOS IntRP chain is not servicing the CD
IRQ, so CdSync never completes. Distinct from the CD-response-value bugs fixed
today; a BIOS-IRQ-chain / libcd-handler matter. Documents the next step and
the full session tally in docs/kula-world-findings.md.
