docs: Add recent-workflow-doc-creator workflow example

[awlevin]

Summary

This PR adds the recent-workflow-doc-creator workflow as an example in the examples/workflows directory.

About This Workflow

The Recent Workflow Documentation Creator is a scheduled workflow that automatically creates GitHub pull requests to document recently deployed Vellum workflows. It demonstrates several advanced Vellum patterns:

Key Features

• Scheduled Trigger: Runs daily at 10:00 AM Mountain Time using a cron schedule
• Map Node Pattern: Processes multiple deployments concurrently (max concurrency of 4)
• Tool-Calling Agent: Uses Claude with GitHub integration tools (via Composio) to:
  • Create new branches
  • Commit workflow code and README files
  • Open pull requests
• Parallel Outputs: Returns multiple outputs simultaneously (PR URLs, comments, deployments JSON)

Workflow Flow

Scheduled Trigger → FetchRecentDeployments → ProcessDeployments (Map) → {
    DeploymentsOutput,
    CommentsOutput,
    PrUrlsOutput
}

Why This Example is Useful

1. Demonstrates scheduled workflows with cron triggers
2. Shows how to use Map Nodes for parallel processing with subworkflows
3. Illustrates Tool-Calling Nodes with external integrations (GitHub via Composio)
4. Examples of custom node displays with icons and colors
5. Shows accessing the Vellum client context for API calls within nodes

This workflow is perfect for teams who want to automate documentation of their workflows as they're deployed.

Provide missing node/trigger modules for workflow

The new example workflow imports .nodes.* and .triggers.scheduled, but the recent-workflow-doc-creator directory only contains README.md and workflow.py (no nodes/ or triggers/ subpackages anywhere in the repo per rg/ls). Importing this workflow will immediately raise ModuleNotFoundError, so the example cannot run or be opened in the SDK. Please add the referenced node and trigger definitions or adjust the imports.
