feat(models): disable giga potato models

[kilo-code-bot]

Summary

• Sets status: 'disabled' on giga_potato_model in src/lib/providers/gigapotato.ts
• giga_potato_thinking_model inherits disabled status via the object spread, so both models are disabled with a single change
• Removes giga-potato and giga-potato-thinking entries from the openrouter-models-sorting.approved.json approval snapshot, since disabled models are excluded from the enhanced model list
• Updates forbiddenFreeModelResponse message from "This is not a free model" to "The free period of this model ended"

Verification

• pnpm typecheck — passed (no errors)
• pnpm lint — passed (0 warnings, 0 errors across all packages)
• pnpm format:check — passed
• The approval snapshot test (openrouter-models-sorting) was updated to match the new output: disabled models are filtered out by kiloFreeModels.filter(m => m.status === 'public') in getEnhancedOpenRouterModels

Reviewer Notes

The giga_potato_thinking_model definition spreads giga_potato_model, so disabling the base model automatically propagates to the thinking variant — no separate status change needed. The preferredModels array already guards against this with a runtime === 'public' check, so giga-potato-thinking is also removed from the preferred list automatically.
