Add RecordNodeHelpData feature

[zeusongit]

Purpose

Summary

Introduce a debug-only RecordNodeHelpData command to capture node help artifacts. Implements RecordNodeHelpData in DynamoViewModel which validates a single selected node, computes a minimum qualified name, exports a workspace image (overlaying 3D background with graph), saves a sample .dyn, and generates a markdown (.md) help file. Temporary images are cleaned up and toast notifications report success/errors. Wire up the command (RecordNodeHelpDataCommand) in InitializeDelegateCommands and expose the DelegateCommand property, and add a corresponding menu item in DynamoView.xaml. Files are written to doc/distrib/NodeHelpFiles/en-US by default.

Feature Details

When triggered, the feature:

1. Validates that exactly one node is selected (shows toast notification if not)
2. Generates three files using the node's minimum qualified name:
   • {NodeName}.md - Markdown documentation with node description and image reference
   • {NodeName}_img.jpg - Workspace screenshot with 3D background overlay
   • {NodeName}.dyn - Current workspace saved as sample graph
3. Outputs files to doc/distrib/NodeHelpFiles/en-US/
4. Displays a toast notification with the short node name and generated file names

Declarations

• Is documented according to the standards
• The level of testing this PR includes is appropriate
• Changes to the API follow Semantic Versioning and are documented in the API Changes document.

Pull request overview

This PR adds a debug-only feature to Dynamo for capturing node help documentation artifacts. The feature allows developers to select a single node and automatically generate the three required files (markdown documentation, sample graph, and screenshot) needed for node help documentation.

Changes:

• Implements RecordNodeHelpData command in DynamoViewModel to validate selection, generate files using minimum qualified name, and provide user feedback
• Adds command infrastructure by wiring up RecordNodeHelpDataCommand in InitializeDelegateCommands and exposing the DelegateCommand property
• Adds a new menu item "Record Node Help Data" to the Debug menu in DynamoView.xaml

Question: Is there any way to make this not in a debug menu for broader use? I think this would be fantastic for the broader community, Eg. Package authors.

I feel this would seem out of place outside the debug mode, maybe we can surface this and let package authors build Dynamo locally, to leverage this?

I think I can probably modify the monocle code to use an invocation of this new mode?

I think of Revit package authors. It is very difficult to build a debug build and load in Revit
