docs: expand dashboard check-in prompts

[Jammy2211]

The Nerves dashboard check-in prompt now supports an ongoing working conversation: a default domain review, focused follow-ups, concrete next actions and existing approval boundaries. The wording was reviewed and approved by the user.

Tracks PyAutoLabs/PyAutoBrain#484. Dashboard navigation and deferred restructuring are unchanged. No merge or publication is authorized.

Scripts Changed

• scripts/board.py
• test_autonerves/test_board.py

Validation

• 238 tests passed.
• All thirteen owner prompts match the approved specification exactly; rendered preview/copy composition preserves the full text and work links.
• git diff --check passed.

Readiness

Heart YELLOW at 2026-10-07T06:49:56.708128+00:00. The previous checkout-behind RED findings are cleared.

• manifest drift: shared-standards blocks (generated) — 2 mismatch(es) vs PyAutoMind/repos.yaml
• release validation stale: source moved since rehearsal (PyAutoNerves, PyAutoFit, PyAutoArray, PyAutoGalaxy, PyAutoLens)

The human instructed “those are fixed, so continue” after these existing readiness findings and the requested development-shipping action were presented. Proceeding with development PRs only; no merge or release is authorized.
