feat(minimap): add node execution status visualization (#9187)

## Summary

Added visual indicators (colored borders) to the MiniMap to display the
real-time execution status (running, executed, or error) of nodes.

## Changes

- **What**: Added visual feedback to the MiniMap to show node execution
states (green for running/executed, red for errors) by integrating with
`useExecutionStore` and updating the canvas renderer.

## Review Focus

Confirmed that relying on the array `.includes()` check for
`executingNodeIds` in the data sources avoids unnecessary `Set`
allocations during frequent redraws.
