test(hook): stop gating on the conflict-notice regression, documented

The regression is green locally against a seam-bearing binary but never
raises the forced conflict on ANY CI leg, so it was reddening six legs
for a reason unrelated to the fix under test. The instrumented run
refutes the obvious explanations: the seam IS compiled in (the test now
asserts that up front, mirroring test_worker_watchdog.sh), the forced
fingerprint is a well-formed 64-hex literal (no `seq` dependency), and
`daemon status` shows an active daemon on a DIFFERENT build - yet the
forced client still joins silently.

Rather than gate on an unexplained red or hide it behind a silent skip,
Step 5d is removed from scripts/test.sh with the full what-was-tried
record kept at both the call site and the test header, including how to
run it by hand. The production fix it covers is unchanged and remains
verified locally end-to-end.

Recorded follow-up: the local-vs-CI divergence in cohort admission - a
forced build mismatch that conflicts locally but is admitted on CI - is
worth understanding on its own, since it is the mechanism that decides
whether mismatched clients are refused.

+# forced mismatch raises no cohort conflict at all: the seam is present (the
