Publish verified Grida bindings and regular token schedules

[softmarshmallow]

Grida's live discovery now lists GPT-6 Sol, GPT-6 Luna, GPT-6.1 Sol and Gemini Nano Banana 2.1. Add their provider bindings, including text-only limits for the three GPT models and generation/edit schemas for Nano Banana.

Also synchronize Grida's published cache-write components for GPT-5.6 Sol/Terra/Luna and GPT-6 Astra, and its verified regular Gemini 3.7/3.8 Flash token prices. Existing input/read/output rates are preserved in the four cache corrections. This changes only Grida provider records and their coverage; native facts, release dates, all other provider prices and the existing 65-model catalogue are unchanged.

Sources, checked against the live service on 2026-10-14:

• Authenticated model discovery
• Operation schemas
• Public API reference

Validation: catalogue build/check, 276 tests, pinned formatting, and full semantic diff review. This verifies advertised contracts and prices, not exhaustive inference behavior. No paid calls.
