Summary

• Adds an in-app notification to normalUnconditionalNotifications in apps/web/src/lib/notifications.ts announcing that StepFun Step 5 Preview is free in Kilo.
• Sets suggestModelId: 'stepfun/step-5-preview-free', so the extension and CLI can offer the model directly. Follows the Nemotron and stealth Opus promo entries.
• Targets extension and cli, matching the Nemotron promo.
• expiresAt is 2026-10-22T08:00:00Z (two weeks out). This is a placeholder display window, not a confirmed end date for the free offer; adjust it if the free period is known.
• Exports normalUnconditionalNotifications so a test can check the suggested model.

This PR does not depend on the preferred-list PR (#7312). The model ID is written as a literal, matching the existing entries, so this branch builds against main on its own.

Verification

• apps/web/src/lib/notifications.test.ts passes (3/3), including a new check that the suggested model is a public free model in kiloExclusiveModels (isKiloExclusiveFreeModel).
• apps/web tsgo --noEmit passes.
• oxfmt --check and git diff --check clean.
• Ran the suite with the repo's apps/web/.env.test and without the DB setup hooks; no Postgres is available in this environment.

Status: No Issues Found | Recommendation: Merge

Executive Summary

Reviewed the new StepFun Step 5 Preview free-model notification and its test; the suggested model ID resolves to a public, free Kilo-exclusive model and the server-only import in the test is mocked by the Jest config.
