docs: vGPU bring-up size/state traps (FB units, GART, modeNum parity)
Record the three independent guest-visible values that broke stock-driver
bring-up: FB info kilobyte-vs-byte units (1024x framebuffer over-report),
multi-GiB GPU GART allocation, and odd shared nvClip modeNum (clears the GL
client's init bits so buffer maps fail). Each has a different diagnostic
signature; the note separates allocation-size, userspace mapping-gate, and
host VAS-translation failures.
Evidence: c15-c26 bring-up, commits 8c7bf295/d1dc85a2/91aa8d91 and
handoff-meta-plan.md CONT.435-CONT.441.
