docs: refresh status, supersede stale material, link the CUDA analysis
* Status now matches the live state: guest driver probe and nvidia-smi work;
cuInit/device queries work; cuCtxCreate returns 999 because the emulated
engine list is missing the async copy engine (COPY14). The userspace
libcuda segfault is recorded as solved, with its mechanism (an RM
allocation reply must echo request parameters; zeroing them corrupted the
caller's saved frame pointer).
* Correct the emulation claims: only a subset of RM controls are
special-cased; the rest return a success reply with zeroed parameters whose
consumed fields are still being corrected; allocation replies are coherent
but no server-side object model exists.
* Add the eight-point emulation checklist and reply-fidelity ladder as
explicit gates, documented in userspace/cuda and linked from the
architecture, implementation and operations docs.
* Fix operational errors: build/test commands, module load order, mdev type
names, LFS references, debugfs claims, in-repo firmware claims, CI claims,
portability matrix (guest status, config layout, userspace driver facts).
* Mark historical material: one superseded banner per legacy document with a
pointer to its replacement; STATE.md marked as a 2026-09-21 snapshot.
* Wiki: fix the index, add status banners and in-place factual corrections
(msgq transport vs legacy mailbox, BAR definitions, error statuses,
migration, glossary), and note the archived 2023 imports.
