fix: remove Ollama template-based tool support gate (#11905)

* fix: let explicit capabilities.tools override Ollama template tool detection

The Ollama provider checks the model template from /api/show for a
`.Tools` placeholder to decide whether to pass tools to the API. For
newer models (e.g. qwen3.5) whose templates may not yet include
`.Tools`, this silently strips tools from the request — even when the
user explicitly sets `capabilities: tools: true` in config.yaml.

Use nullish coalescing so an explicit capabilities.tools setting always
wins, with the template heuristic as a fallback.

* remove verbose comments

* remove templateSupportsTools check; trust upstream tool support detection

* fix: remove extra blank line to pass prettier check
