Example: Align-Check Only

User request: I already wrote a cover letter; check whether any claim overshoots my manuscript before I send it.

Recommended module sequence:

1. align-check

Commands:

uv run python -B $SKILL_DIR/scripts/cover_letter.py --mode align-check --letter cover_letter.md --manuscript main.tex --json

Expected output:

• JSON list of align-check issues (or LaTeX-comment block when --json omitted).
• For each unsupported claim: exact letter quote, manuscript section anchor (or none), claim_strength label, missing_evidence array, and an allowed_wording rewrite that stays within manuscript scope.
• Exit code 0 (all claims supported), 1 (some observed/unsupported but no major), or 2 (at least one Major-severity issue).
