Add MiMo V2 Pro/Omni models and family entries

Register two new MiMo V2 models and update model family values. Added "mimo-pro" and "mimo-omni" to ModelFamilyValues in packages/core/src/family.ts, and added corresponding TOML model descriptors under providers/opencode-go/models: mimo-v2-pro.toml and mimo-v2-omni.toml. The Pro model includes very large context (1,048,576) and tiered costs for >200k context, while the Omni model exposes multimodal input (text, image, audio, pdf) and a large 262,144 context. Both files set metadata (release_date, last_updated, knowledge cutoff, open_weights) and define interleaved reasoning field, costs, limits, and modalities.
