test(fireworks-ai): lock reasoning controls

[rekram1-node]

Summary

• audit every Fireworks provider catalog entry against the current Fireworks reasoning API reference and serverless availability documentation
• lock the exact reasoning controls for all 13 reasoning models and routers in a focused catalog regression test
• reject reasoning options on non-reasoning entries and require explicit review when Fireworks entries are added or removed

Audit result

• 13 catalog entries reviewed; 13 reasoning-enabled and 0 non-reasoning
• 7 toggle-capable entries, 4 effort-only entries, and 2 toggle-plus-effort entries
• no reasoning flag or availability corrections required after the reasoning controls merged in feat(fireworks-ai): add reasoning options #2080
• no live endpoint testing performed because FIREWORKS_API_KEY is unavailable

Validation

• bun validate
• bun test packages/core/test/fireworks-ai-catalog.test.ts
• git diff --check
