[Enhancement]: Support for MCP Tasks

[nileshtrivedi]

What features would you like to see added?

MCP spec now has a standard for long-running tool calls, called, Tasks (currently experimental).

This was standardized in modelcontextprotocol/modelcontextprotocol#1686.

Supporting this would remove the need for fixed timeouts or agentic progress-tracking for long-running MCP tool calls.

Very interesting, I was trying to figure out how to design my MCP tool differently because it takes so long to return the answer but this seems like a perfect solution for that. Would be nice if this could be included in the roadmap, but it probably has to not be experimental to be added.
