To verify the fix manually:
1. Configure a custom OpenAI-compatible provider that doesn't return model limits
2. Use any agent (e.g., sisyphus) with a model from that provider
3. Confirm no maxOutputTokens must be >= 1 error occurs
4. Verify maxOutputTokens falls back to bundled snapshot values (e.g., 32768 for kimi-k2.5)

## Summary by cubic
Fixes maxOutputTokens errors with some OpenAI-compatible providers by treating zero or negative `limit.output` as unknown. `readRuntimeModelLimitOutput()` now returns `undefined` for non‑positive values so `getModelCapabilities()` falls back to bundled snapshot limits.

<sup>Written for commit 6c3308aab3904b1e91ea29fba3487e77865c689b. Summary will update on new commits.</sup>
