Run with --all-files --hook-stage manual, as in CI.
- typos: keep the DSO hash as one token instead of a split identifier.
- clang-format and markdownlint fixes for the prefill notes and the dmv13
packer.
- mypy: declare the fake processor's tokenizer; annotate a test list.
- Imports: pybase64 in the route capture script; allow pickle in the two
tests whose subject is a pickling round trip.
- torch.accelerator.synchronize instead of torch.cuda.synchronize in the
prefill preparation teardown and the expert-cache and MTP Q8 tests.
