userspace/cuda: complete the analysis pass
* Name recovery: name_candidates.py proposes the hand-written API-layer
implementation for each exported wrapper by grouping version variants and
intersecting their callees; 180 high-confidence proposals recorded in
annotations/name-candidates.tsv, 29 of them body-verified and promoted to
names.tsv with evidence in subsystems.tsv.
* Engine records: identified the 0x14-byte per-engine descriptor, mapped its
fields (kind, engine type, instance, class id, CE caps) and the existence
callback, and documented how the missing async copy engine (COPY14) leaves
the secondary record zeroed and blocks context creation (docs/05 section
3.7, public-safe).
* Targeted type recovery: AnalyzeFunctions.java runs the parameter-ID
analyzer over a curated list of 80 functions; 16 improved materially and
the typed decompilations are kept under the version run tree.
* Cross-version: cudatool.py fdematch measures how names transfer between
patch versions (570.144 -> 570.211.01: exports 100%, verified internals
~70%, generated wrappers must be re-resolved by relocation, never by
address arithmetic); documented in the upgrade playbook.
* Corpus tooling: diff_corpus.py (version-to-version corpus diff) and
subsystem_digest.py (per-subsystem call trees).
* Deprecate the old per-version helpers whose address handling and analysis
timeout produced wrong results.
Generated corpora and typed outputs remain untracked under the version run
tree.
