feat(ui): add cancelled status and improve MCP resource docs

- Add cancelled status to UI module for marking tasks cancelled without deletion
- Improve MCP server resource documentation with implementation examples
- Update architecture.mdc with detailed resource management info
- Add comprehensive resource handling guide to mcp.mdc
- Update changeset to reflect new features and documentation
- Mark task 23.6 as cancelled (MCP SDK integration no longer needed)
- Complete task 23.12 (structured logging system)

Direct integration with the MCP SDK would be redundant and potentially counterproductive since:\n\n1. FastMCP already encapsulates the necessary SDK functionality for tool registration and resource handling\n2. The existing FastMCP abstractions provide a more streamlined developer experience\n3. Adding another layer of SDK integration would increase complexity without clear benefits\n4. The transport mechanisms in FastMCP are already optimized for the current architecture\n\nInstead, we should focus on extending and enhancing the existing FastMCP abstractions where needed, rather than attempting to bypass them with direct SDK integration.\n</info added on 2025-03-31T18:49:14.439Z>",
