userspace/cuda: add CUDA userspace driver analysis, tooling and name maps
Add the analysis of the NVIDIA CUDA userspace driver used by Open-IOV VMs:
* docs/01-08: architecture (layers, object model, threads, sync, memory,
channels, launch), build and execution model, the driver/kernel/GPU
interface contract, virtualization approaches, the 570.144 decompilation
map with the corrected libcuda crash path and the current engine-topology
blocker, tooling, and a version-upgrade playbook.
* tools/: version-agnostic toolchain - stdlib ELF/interface toolkit
(exports, unwind-table function map, wrapper resolution, version delta,
crash address decode), callgraph walker, corpus annotator, and Ghidra
analysis/decompilation/name-map scripts with resumable parallel drivers.
* 570.144/annotations/: our name map (exports + resolved wrappers + verified
internals) and subsystem index, tracked so naming work accumulates.
* READ-ME-FIRST.md: reading guide with the fast lookup recipes.
The full decompiled corpus and annotated corpus stay untracked (vendor-
derived, gitignored under the version run/ tree).
