test(docs): align opencode-go preset assertions and docs with minimax-m3 + mimo-v2.5

Update bundled-preset tests (providers.test.ts, config-io.test.ts) to the
new orchestrator/observer models and assert the new max variants. Refresh the
stale generated-config example and Observer guidance in docs/README.

 ### After Installation
 
-The installer generates both OpenAI and OpenCode Go presets, with OpenAI active by default (using variant-aware GPT-5.6 models, including `gpt-5.6-terra (medium)` for Orchestrator, `gpt-5.6-sol (high)` for Oracle, `gpt-5.6-luna (medium)` for Fixer, and `gpt-5.6-luna` variants for other specialists). To make OpenCode Go active during install, run `bunx oh-my-opencode-slim@latest install --preset=opencode-go`. That preset uses GLM-5.1 for Orchestrator, so the installer also enables Observer with `opencode-go/kimi-k2.6` for visual analysis. To switch providers later or build a mixed setup, use **[Configuration Reference](configuration.md)** for the full option reference and the preset docs for copyable examples.
