docs: run the gate CI runs, and bindings.rs is run

Two one-line corrections the wave's last review surfaced, both about a claim
being stated in more than one place.

.claude/skills/code-review/SKILL.md told every reviewer and every wave agent to
run `cargo clippy --workspace --all-targets` with no `-D warnings`. Clippy exits
0 on warnings, so the committed local gate was green on exactly the input CI is
red on. This is not one person's shell mistake, it is the instruction: a
reviewer following the skill as written would report clean and be wrong, which
happened on PR #71. Also adds --no-fail-fast, since fail-fast hides blast radius.

README.md was a sixth copy of "bindings.rs is never run", which PR #70 corrected
in five places -- its grep missed README, and PR #72 then rewrote the sentence
four lines above and carried the wrong half forward. Neither PR is at fault
individually; it is an interaction between two branches, and it is the exact
failure the corrected fact is a monument to.

Plus doctrine(a_weak_check_and_a_strong_one_agree_until_the_defect): five
instances this wave, one mistake -- a check written against the failure you
imagined rather than the outcome the user sees. The weak and strong checks agree
on every input anyone tried and diverge only on the input that is the defect.
