feat(providers): add OpenAI GPT-5.6 Sol, Terra, and Luna models

[waleedlatif1]

Summary

• add GPT-5.6 Sol, Terra, and Luna to the openai provider in models.ts
• Sol is the new flagship (recommended: true, moved off gpt-5.5), Luna is speed-optimized
• pricing, context window (1.05M), max output (128K), and reasoning-effort levels (incl. new max tier) verified against OpenRouter's live model API and cross-checked against announced pricing

Type of Change

• New feature

Testing

Tested manually — bun run lint passes, verified reasoningEffort/verbosity fields are consumed by openai/core.ts, confirmed no test suite hardcodes an exhaustive model list that would break.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

PR Summary

Low Risk
Static provider catalog updates only; no runtime logic changes beyond how existing metadata drives model pickers, pricing, and request sanitization.

Overview
Registers GPT-5.6 Sol, Terra, and Luna in the OpenAI provider catalog with pricing, 1.05M context, 128K max output, and reasoning effort options through a new max tier (plus verbosity).

gpt-5.6-sol is now the OpenAI recommended default; recommended: true is removed from gpt-5.5. gpt-5.6-luna is marked speedOptimized.
