trace-to-skill v0.1.105

Adds issue-heat, a recency-weighted GitHub issue movement report for Codex maintainers. It complements issue-map by showing what is moving right now, ranking recent clusters by recency, labels, comments, reactions, severity, and the first support artifact to generate.\n\nProof before release:\n- npm run check: 106 tests plus doctor/lint/smoke checks passed\n- YAML parse, git diff --check, npm pack --dry-run passed\n- live openai/codex issue-heat verified Windows helper/plugin hot clusters while excluding weak_evidence and premature_completion from hot output
