FN-7847: add pricing for GLM-5.2, MiniMax-M3, and Kimi K2.6

Adds static MODEL_PRICING rows for three previously-unpriced models so their token usage renders a dollar cost instead of "—" in the dashboard.

- Add zai:glm-5.2, minimax:minimax-m3, and kimi-coding:kimi-k2.6-preview pricing rows to MODEL_PRICING, sourced from each provider's public pricing docs
- Bump pricingAsOf to 2026-07-11
- Add regression tests asserting costFor() prices these three models (not unavailable) and that lookupPricing() resolves them by provider-normalized and bare model-id keys
- Add a minor changeset documenting the pricing addition for @runfusion/fusion release notes
