test(bios): integrate pinned BIOS read-protection baseline

Browse source 
Add --suite bios with hash-verified upstream files and the ARM evaluation checkpoint at 0x08000248. Preserve the r12=0 assertion, original BIOS boot, and all test bytes. Add synthetic adapter and CLI regressions.

On Darwin arm64 the public ROM fails test 1 in debug and release after 64 steps and 543 nominal cycles. Document that this tests protected reads of Nintendo firmware opcodes, not general BIOS service compatibility. Online and offline preparation agree; 39 Python tests pass. Core behavior is unchanged.
