URL: https://github.com/apache/superset/pull/36553
### SUMMARY
Enable FastMCP background task protocol (SEP-1686) for MCP tools, allowing
long-running operations to execute asynchronously with progress reporting.
**Changes:**
- Upgrade `fastmcp` dependency from `>=2.13.0.2` to `>=2.14.0`
- Add `task` parameter to `@tool` decorator infrastructure in both
`superset_core.mcp` and `core_mcp_injection.py`
- Enable `task=True` for three long-running tools:
- `execute_sql` - SQL query execution
- `generate_chart` - chart creation with validation and preview generation
- `generate_dashboard` - dashboard creation with chart layout
**Benefits:**
- Tools can now run in the background without blocking the MCP client
- Progress reporting via `ctx.report_progress()` shows step-by-step execution
- Better UX for complex operations that may take several seconds
- Clients can track, cancel, and retrieve results asynchronously
### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
N/A - API change, no UI modifications.
### TESTING INSTRUCTIONS
1. Install updated dependencies: `pip install -e .[fastmcp]`
2. Start the MCP server: `python -m superset.mcp_service`
3. Connect with an MCP client that supports the task protocol
4. Execute `execute_sql`, `generate_chart`, or `generate_dashboard`
5. Verify that progress is reported and operations complete successfully
