docs(fleet): ci-red is deployed engine — advance the stamp to crew@4da17c4

Refs #189 — the post-merge, triage-owned task, now reachable: heavy-duty/crew#64
merged at 4da17c49594c2d86bd3793fa3567846cbca38e90.

#190 wrote the ci-red wake into FLEET.md deliberately marked on paper, per this
file's convention for a spec that is not yet running, and left the reconciliation
stamp at crew@01fb49c because advancing it to a SHA that did not carry the wake
would be the drift #187 exists to remove. crew#64 has merged, so both halves flip:

- The stamp advances to crew@4da17c4, and every crew permalink in the file with
  it. A stamp and its evidence links naming different trees is worse than no
  stamp: the reader diffs the wrong engine and finds no drift because the tree
  they were pointed at is the one the prose was written against.
- The four on-paper markers go: the duty-order caveat, the ci-red bullet's
  parenthetical, the Build bullet's "once ci-red deploys", and the closing
  paper inventory — which now names one remaining paper wake, the notifier's
  needs-ruling queue, not two.

The Build bullet is not a pure marker removal. crew#64's last review round
changed what it has to say: the operator ruled the round gate a whitelist, so
the wake admits a green head OR one with no checks configured, and holds a red
head AND one whose check has not finished. Copying the old "never a round at a
red head" through the flip would have shipped a fresh inaccuracy on the same
commit that claims the file is reconciled. The ci-red bullet gains the matching
sentence from the other side: an unfinished check is not a red head and wakes
nothing, because nothing has failed yet.

Verified at the stamped SHA rather than assumed: duty.sh's header carries
attention → … → resume → ci-red → build (and says it is what this file is
reconciled against), shared/README.md's duty order matches, and notify.sh's
only label filter is still state:needs-human — which is what keeps the
remaining paper claim true.

18/18 test files pass; changelog_fragment_problem OK (it caught a 387-char
entry against the 300 bound, now split); shellcheck, actionlint self-ref and
git diff --check clean.
