Description
### Description
As discussed in https://github.com/apache/lucene/pull/13104, the current API allows for changing the configuration of token streams after construction(such as `ShingleFilter`), but it should be set only during construction. Perhaps we can impose some constraints on the API to prevent more such cases in the future.
Contributor guide
Research direction
Start by reviewing the ShingleFilter API and the discussion in pull request 13104 to identify which token-stream settings can currently change after construction. Done means the intended construction-time-only constraint is defined and applied consistently, with affected API behavior covered by the relevant tests.
