Fixes
AST tools: global npm module resolution
module.globalPaths.push() doesn't work after Node.js startup. Fixed by setting process.env.NODE_PATH then calling Module._initPaths() to force path re-initialization.
python_repl: CJS path resolution
import.meta.url is undefined in CJS bundles, causing fileURLToPath(undefined) to throw. Added fallback to __dirname for bundled context and OMC_BRIDGE_SCRIPT env var support.
