comments: replace law idiom with the mechanism it encoded

Every comment that cited a named law, an incident date, or an
internal nickname now states the underlying mechanism and why it
matters, generically: curl exit-0 artifacts and byte-count gates,
argv-in-/proc secret exposure, tag mutability vs digest pinning,
shape-specialized kernels refusing uncompiled slot counts, MTP heads
as file tensors no flag can supply, drafter/slot coupling as an
engine property, pkill -f matching its invoker, pinned-RAM pairing
with LimitMEMLOCK, one-encoding-per-table, the short-run first-token
noise floor, and the protected-expert rule. No behavior change:
comment/string text only; suite green (371 tests).
