Monty.SensorModules.SensorModule.TransformContext (ExTbpMonty.Core v0.1.0)

What a transform knows about the step it is transforming.

Mirrors tbp/monty/sensor_modules/sensor_module.py::TransformContext: the random stream, where the agent and this sensor are, and the two flags that decide whether the step is one to learn from and whether a failure inside a transform should be raised or reported.

Monty passes its one runtime rng here. The port passes the stream this sensor may draw from at this step (Monty.Context.rng_for/2), so a transform that samples is reproducible from the episode seed alone (docs/monty-differences.md §2.1).
