refactor: remove CommonJS ripgrep launcher and spawn binary directly

Replace the ripgrep_launcher.cjs intermediary with direct binary execution.
This simplifies the ripgrep module by spawning the binary directly instead
of going through a Node.js subprocess wrapper. Add platform-specific binary
path resolution to handle both Unix and Windows environments.
