Greptile Summary

This PR restores output-picker interactions and improves access to selected nested outputs while reorganizing the advanced MCP action.

• Normalizes selected output values and pins selected outputs in a dedicated group for quick deselection.
• Adds option-level selection handling shared by the small and medium picker variants.
• Moves “MCP Server (Advanced)” into a final Advanced section without changing its availability guards.
• Expands focused tests for nested selection, selection preservation, deselection, and the medium picker.

Confidence Score: 5/5

The PR appears safe to merge, with the restored picker behavior and MCP menu reorganization preserving the relevant selection and availability contracts.

The output options now use the real Combobox selection path consistently across picker sizes, selected nested outputs remain directly removable, existing selections are preserved, and the relocated MCP action retains its previous conditions and behavior.
