fix(auxiliary): forward custom_providers to compression model context-length detection (#25359)#25494

…-length detection When auxiliary.compression.provider is "auto", the compression model reuses the main model's provider and base_url. The main model's context_length was correctly picking up custom_providers per-model overrides (via _custom_providers stored during __init__), but the auxiliary compression model's context-length detection path in _check_compression_model_feasibility was not passing custom_providers, causing it to skip step 0b and fall through to models.dev. This meant that for providers like NVIDIA NIM where the user has a per-model context_length in custom_providers (e.g. 196608 for minimax-m2.7), the auxiliary model would use the models.dev value (204800) instead of the user-configured one — a subtle discrepancy that could lead to silent compression issues when the auxiliary model doesn't actually support the detected context length. Fix: pass self._custom_providers (already stored as an instance attr during __init__) to the get_model_context_length() call for the auxiliary compression model.

get_model_context_lengthacceptscustom_providers(so users with custom provider configs get correct context-length resolution), but_check_compression_model_feasibilitywas calling it without passing custom_providers — so users on custom providers got wrong context-length values for compression decisions.5-line forward fix.
