/**
 * crewx hook-dispatch — CLI subcommand invoked by Claude/Codex PreToolUse hook.
 *
 * Reads stdin JSON from the provider, loads HookPlugins from crewx.yaml,
 * evaluates them, and writes stdout JSON response back.
 *
 * Protocol:
 *   stdin  → ClaudeHookInput JSON
 *   stdout → ClaudeHookOutput JSON
 *   exit 0 → allow, exit 2 → deny
 *
 * Security (M1):
 *   --provider argument is REQUIRED. Missing → process.exit(1) fail-closed.
