Add TypeScript types for parsers

**Feature request**
It would be great to have timeout for models.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_timeout` with default `false`.

The title asks for TypeScript types for parsers, while the body asks for a model timeout and an enable_timeout config option. No files, tests, or entry points are named, so first clarify which feature is intended and locate its configuration and model-loading entry points. Done should match the confirmed scope and include coverage for the requested behavior.
