Telemetry: API node usage details (execution_start + run_button_clicked)

[benceruleanlu]

Summary

• Add API node usage to run_button_clicked and execution_start telemetry.
• Include has_api_nodes (boolean) and api_node_names (canonical nodeDef.name array).
• Compute metrics within a typed reducer for maintainability; stable ordering for names.

Implementation

• types: src/platform/telemetry/types.ts
  • Extend RunButtonProperties and ExecutionContext with has_api_nodes, api_node_names
• provider: src/platform/telemetry/providers/cloud/MixpanelTelemetryProvider.ts
  • Build NodeMetrics in single traversal using reduceAllNodes
  • Use canonical names (nodeDef.name), dedupe, sort
  • Emit fields on app:run_button_click and execution_start

Notes

• Subgraph and total node counts unchanged.
• Lint and typecheck passed locally.

Requested review

• Confirm Mixpanel property schema alignment for new fields.
• Approve naming: has_api_nodes, api_node_names (alternatives: api_node_types).
