[Fix] OpenCode Go context meter shows incorrect limits

[zoomote]

​Created by Roomote. Follow up by mentioning @roomote, in the web UI, or in Discord.

What changed

All 35 models currently returned by OpenCode Go now have complete metadata in the single opencodeGoModels registry, including limits, capabilities, pricing, and descriptions. Live endpoint metadata still overrides volatile fields when supplied. Qwen models use the Messages API where required, while GPT-5.6 Luna, Grok, and Muse Spark models use their documented Responses API route.

Independent registry expectations cover the curated metadata, including corrected GLM-5.3 Flash and HY3 prices, Luna's max-output control, Muse Spark 1.3, and the newly listed Omen Alpha model.

Why this change was made

Models without a registry entry inherited a generic 200k context window, causing incorrect context percentages. Incorrect prices understated displayed costs, while split metadata and incorrect wire-format routing could silently produce inconsistent controls or failed requests.

Impact

The context meter, model controls, cost estimates, and request routing now resolve from one current model registry. Unknown future IDs retain the safe generic fallback until their metadata is curated.

[zoomote]

Consolidated all 33 OpenCode Go model records into opencodeGoModels and removed the separate limits registry/helper. The registry now carries limits, capabilities, pricing, and descriptions for every current live ID, with exact membership and metadata invariants covered by tests. Full workspace tests, lint, and type checks pass.

📝 Summary

Summary by CodeRabbit

• New Features
  • Expanded OpenCode Go model availability with additional Qwen, GLM, Kimi, DeepSeek, Grok, Muse, and other models.
  • Added model-specific context limits, token limits, pricing, descriptions, and capability details.
  • Added support for maximum-token configuration on GPT-5.6 Luna.
  • Added Anthropic Messages compatibility for Qwen3.8 Flash and Responses compatibility for additional Grok and Muse models.
• Improvements
  • Model information now reflects registry and service-provided capabilities more accurately.

Walkthrough

The Opencode Go registry adds model metadata for new providers, expands Anthropic and Responses routing, and enables registry-resolution tests for model capabilities, limits, and pricing.

Changes

Opencode Go model support

Layer / File(s)	Summary
Expand the native model registry packages/types/src/providers/opencode-go.ts	The registry adds model entries, updates descriptions, and enables supportsMaxTokens for gpt-5.6-luna.
Update model format routing packages/types/src/providers/opencode-go.ts, packages/types/src/__tests__/opencode-go.test.ts, src/api/providers/__tests__/opencode-go.spec.ts	qwen3.8-flash uses Anthropic Messages format. Grok and Muse models use OpenAI Responses. qwen3.5-plus remains OpenAI-compatible.
Validate registry resolution src/api/providers/fetchers/opencode-go.ts, src/api/providers/fetchers/__tests__/opencode-go.spec.ts, packages/types/src/__tests__/opencode-go.test.ts	Tests verify native metadata resolution and complete metadata for the expanded registry. The parser documentation describes the resolution order.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to be8b7

The model registry improves routing and metadata coverage, but incorrect HY3 and GLM-5.3 Flash prices would materially understate displayed cost estimates. Correct these values and their test expectations before merging.

[zoomote]

Addressed the latest CodeRabbit findings in 3541bb2b9: corrected GLM-5.3 Flash pricing, corrected both HY3 aliases, and added verified omen-alpha metadata plus exact catalog/registry coverage. The two new inline threads were replied to and resolved; all four CodeRabbit threads are now resolved, with no new unresolved feedback after the final refresh.

The description-template warning remains non-actionable because the repository has no checked-in PR template and no linked issue was supplied. Focused tests, the full workspace suite, lint, type checks, and every required GitHub CI check pass. The remaining PR gate is fresh human maintainer or CODEOWNER approval.

193-193: 🎯 Functional Correctness

Add omen-alpha to the complete-registry fixture.

The exact-key assertion requires every model returned by the OpenCode Go /models response to appear in modelIds, but the required endpoint response is unavailable.
