/**
 * Codex hook adapter — `code-audit codex-hook`.
 *
 * Reads Codex's PostToolUse stdin JSON and runs a diff-scoped audit.
 *
 * Phase 0 verification (2026-07-19):
 *   - Source: learn.chatgpt.com/docs/hooks
 *   - PostToolUse is BLOCKING: exit 2 replaces the tool result with feedback
 *   - Matcher in hooks.json: "apply_patch" (Codex's file-editing tool)
 *   - stdin shape: { session_id, tool_name, tool_use_id, tool_input, tool_response }
 *   - tool_input.file_path contains the edited file
 *
 * Exit codes:
 *   0 — no critical violations found
 *   2 — critical violations found (blocking feedback loop)
 *   1 — internal error (adapter crash, not violation-related)
