fix(models): expose static models list so UI renders entries before listModels resolves

The UI was showing 0 models because the adapter only set listModels (async)
without a static models array. The static array is what the UI reads
synchronously to populate the selector — listModels is for refresh.

- Move the fallback list out as STATIC_MODELS (expanded to cover Opus/Sonnet/Haiku 4.x, GPT-4o/5, Gemini 2.5, Grok 4, DeepSeek)
- Set models: STATIC_MODELS on the adapter module
- Keep listK8sModels for runtime refresh from `opencode models` (with STATIC_MODELS fallback on error or empty stdout)
- Add server-adapter.test.ts asserting models is non-empty
- Add models.test.ts coverage for the empty-stdout fallback path

chore: bump version to 0.1.33

Fixes FAR-94.
