Pull request overview

This PR streamlines “tools” across the stack by switching to the OpenAI Responses API function-tool shape end-to-end, simplifying /api/tools to return a raw list, improving the chat tool selector UX, and adding frontend manifest includes resolution for easier module composition.

Changes:

• Flattened tool definitions (frontend + backend) to use { type: "function", name, description, parameters, strict } and updated tool fetching/usage accordingly.
• Added frontend manifest includes resolution with merge/replace/drop collision strategies and accompanying tests/docs.
• Introduced a backend ToolsRouterModule that aggregates multiple tool registries and dispatches tool execution by tool name.
