feat: Implement web_search and image_generation as part of native tool calling

Before Submitting

• I searched open and closed issues and discussions for an existing request.
• I checked whether this already exists on the dev branch or latest source.
• I understand that maintainers want a well-written issue or discussion before any code pull request.
• This request is not a security vulnerability.

Problem

When web_search and image_generation are configured on a model, they should automatically be exposed as part of the model's native tool calling. Currently, the user has to manually toggle these features on for every message/session, even though the model supports native tool calling.

web_search and image_generation are not part of the native tool calling context by default. The user must manually enable them each time, which is error-prone and breaks the flow for models that natively support function/tool calling.

Desired Behavior

If web_search or image_generation is configured (and native tool calling is available), they should be included in the available tool set automatically — no manual toggle required per message.

Why This Matters

Models with native tool calling already handle tool selection correctly — the manual toggle adds unnecessary friction. Consistency: all other tools/functions registered in the workspace are part of native tool calling; the built-in capabilities behave differently. Reduces user error (forgetting to toggle) and makes configured capabilities behave predictably.

Alternatives or Workarounds

Right now, we have a function that has a small LLM deciding if either should be toggled, but its just extra delay and functionality, and it doesnt work everytime since the LLM doesnt always get it right.
