Triage: blocked on a documented pin, not on the package

Different failure mode from the GitHub Actions PRs (#33/#110/#111) — no payload-managed file is touched here, so the control plane is quiet. What fails is coherence:

FAILED tests/coherence/test_pins.py::test_package_json_pins_both_tools    - assert '3.9.6' == '3.8.3'
FAILED tests/coherence/test_pins.py::test_lockfile_agrees_with_package_json - assert '3.9.6' == '3.8.3'

tests/coherence/test_pins.py:7 holds PRETTIER_PIN = "3.8.3" as the single source of truth, asserted against both package.json and package-lock.json.

Why this pin is not just a number to bump

This repository publishes Prettier guidance, so the pinned version is load-bearing in shipped prose. markdown-tooling 1.12's adopt.md documents a Prettier Markdown-printer defect as current behavior — that prettier --write can rewrite an intraword literal underscore (America/New_York) into an asterisk and can edit content inside a code span, citing upstream prettier#7695. That warning drives a documented review control for consumers.

3.8.3 → 3.9.6 is a minor bump spanning several releases. If any of that range changes the Markdown printer's behavior, the shipped guidance becomes wrong — either stale (warning about a fixed bug) or, worse, silently under-warning. So the bump needs a behavioral check against the documented cases, not just a green test run.

What this PR actually needs

• Confirm prettier 3.9.x behavior against the America/New_York and code-span cases documented in markdown-tooling 1.12 adopt.md.
• Update PRETTIER_PIN to match.
• If printer behavior changed, the payload prose must change too — which turns this into a markdown-tooling minor rather than a lockfile bump.
• Re-run prettier --check across the repo; a minor bump can shift formatting and cascade into the Prettier gate.

Left open deliberately.

Automated triage; no code changed.
