Add TypeScript types for parsers

**Description**
Currently routes lacks proper monitoring support.

**Proposed solution**
Add configurable monitoring with sensible defaults.

**Priority**: Low/Medium

The title asks for TypeScript types for parsers, while the body asks for configurable route monitoring, so first reconcile which requirement is intended with the issue author. No files, tests, or entry points are named; locate the relevant parser or route-monitoring code, then confirm the expected defaults and a testable definition of done before starting.
