Summary

• Removes the disabled stepfun/step-5-preview-free Kilo-exclusive model and its STEP_5_PREVIEW_FREE_MODEL_ID constant. isStepModel stays because other StepFun models use it.
• Removes the public stealth/cat-jam Vercel-served stealth model and its fallback reasoning options.
• Updates tests: both IDs are now covered by the existing "removes %s from exclusive models" check. Tests that only used the Step 5 ID as an arbitrary model string now use generic IDs.

Behavior

• stealth/cat-jam is no longer listed, free, or routed through Vercel AI Gateway as an exclusive. If it is still in the Auto Free DB config, getAutoFreeCandidates skips it because it is no longer a free model.
• stepfun/step-5-preview-free is no longer rejected early as a disabled exclusive. It falls through to normal model handling, which is the same path earlier removed exclusives take.

Verification

• pnpm --filter @kilocode/web-shared typecheck
• pnpm --filter web --filter ai-gateway typecheck
• oxlint -c .oxlintrc.json packages/web-shared/src/lib/ai-gateway
• pnpm --filter web test -- packages/web-shared/src/lib/ai-gateway/ packages/web-shared/src/lib/model-allow packages/web-shared/src/lib/organizations/effective-model-access: 104 suites, 1914 tests passed

Executive Summary

Reviewed the removal of the stepfun/step-5-preview-free disabled exclusive and the stealth/cat-jam Vercel stealth model; the deletions are internally consistent with no dangling references or logic regressions.

Verification notes: STEP_5_PREVIEW_FREE_MODEL_ID, stepfun_5_preview_free_model, and cat_jam_stealth_free_model have no remaining references in the repo. Remaining stepfun/step-5-preview usages are the retained non-free variant. isStepModel and isDisabledKiloExclusiveModel remain used and correctly retained.
