[BUG] `ScopedParameterDict` is not pep compatible according to beartype > 0.18

[LaurenzBeck]

🐛 Bug Report

I tried to remove all upper dependency bounds, but polars throws runtime exceptions if updated beyond 0.17.2

💻 Reproducing the Bug

1. update beartype
2. run tests

📄🖼️ Context and Screenshots

ERROR tests/unit/visualizations_test.py - beartype.roar.BeartypeDecorHintNonpepException: Method streamgen.parameter.store.ParameterStore.init() parameter "parameters" type hint <function TypedDict at 0x000002A458B21C60> either PEP-noncompliant or currently unsupported by @beartype.

🤔 Possible Solution

Switch to a different type hint for ScopedParameterDict
