- PR #117929: fix(compression): let model ratios outrank the default cap

Multiple fixes and a bug report addressing a default 256K token compression cap that silently overrides user-configured model_thresholds ratios for large-context models. Several approaches attempt to make explicit user configuration take precedence over the default cap.

## TL;DR
