dsh-session-audit

Folds a single DSH session’s event log into a readable execution audit in one session_audit call: turns/steps, tool-call distribution with success/failure split, token usage, deterministic signals (consecutive failures, exact duplicate calls, hot tools, repeated file reads), and detection of test/build/lint/typecheck commands with actually observed results. Reports come in text, Markdown or JSON (stable schemaVersion). Everything runs locally — no LLM calls, no network requests.
