/**
 * Hook Bridge - TypeScript logic invoked by shell scripts
 *
 * This module provides the main entry point for shell hooks to call TypeScript
 * for complex processing. The shell script reads stdin, passes it to this module,
 * and writes the JSON output to stdout.
 *
 * Usage from shell:
 * ```bash
 * #!/bin/bash
 * INPUT=$(cat)
 * echo "$INPUT" | node ~/.claude/harmony/hook-bridge.mjs --hook=keyword-detector
 * ```
