Tmone Nguyen 124557cc4b fix(combo): context-aware fallback ignores model_context_override (#7933)
* fix(combo): context-aware fallback ignores model_context_override

filterTargetsByRequestCompatibility resolved a target's context capacity through the override-free getResolvedModelCapabilities, so a persisted model_context_override (Feature 5004) never reached the compatibility filter. A provider whose catalog maxInputTokens is a deliberately small client-facing hint (below the real window so coding agents auto-compact, #6191) is then dropped from the fallback pool for large-context requests even when an operator recorded its true larger capacity. With only that provider left after Claude quota is exhausted, the combo returns a hard 503 with no fallback.

evaluateContextLimit now consults the raw override (getModelContextOverride, null when unset) before catalog limits, only when an override exists - so a genuinely-too-small maxInputTokens is still enforced for non-overridden models. Consistent with two other override-aware call sites in this file. Registry values (#6191 client hint) untouched. Tests: override rescues small-catalog target; without override too-small still dropped; existing #6191/#7039 tests pass (14/14).

* fix(quality): extract context-fit evaluation to keep comboStructure.ts under cap

The model_context_override fix grew open-sse/services/combo/comboStructure.ts
past the 800-line file-size cap. Extract evaluateContextLimit() (the
override-then-catalog context-fit check) into a new leaf,
open-sse/services/combo/contextOverrideGate.ts, so comboStructure.ts only
keeps the two call-site wires. No behavior change.
