fix(graph-reviewer): remove duplicated critical checks from warning section

Edge weights, node ID prefix conventions, and tag formatting were listed
in both Check 1 (Schema Validation — Critical) and Check 7 (Quality —
Warning). A deterministic script following check headings would classify
these as warnings, potentially approving invalid graphs. Remove the
duplicates from Check 7 since Check 1 already covers them as critical.
