root c6ef1860cd Add the CPU-vendor divergence reference ...

references/cpu-vendor-divergence.md records where the two x86-64 implementations
diverge: undefined results, vendor-string dispatch, feature-gated decoding,
system-instruction fault timing, and model-specific cost, each stated with what
it changes for reading a binary or writing a specification.

Register it in the routing index, both symptom tables and the route table; add
the coverage row (inferred, no second-vendor host), the route-inventory row
(argued) and the evidence note that every measurement here came from one
implementation.

Append P38 for an undefined result recorded as a defined one, and point
assembly-idioms and hypervisor-observation at the new file.
