Fix test-dispatcher workflow to use safe outputs properly

Q Workflow Optimization Report

Issue Context

This PR addresses issue #12971, where the test-dispatcher workflow was repeatedly failing with "No Safe Outputs Generated" errors. The workflow ran successfully but didn't produce any safe outputs, causing downstream processing to fail.

Failed Run IDs Analyzed

• Run 21547216704 (original issue)
• Run 21547252198
• Run 21547524795

• Run 21547527335
• Run 21547532343
• Run 21547522773

All runs exhibited the same pattern: agent job succeeded but produced no safe outputs.

Root Cause

The test-dispatcher workflow had a safe-outputs configuration with dispatch-workflow capability, but the prompt didn't instruct the agent to actually use it. The original prompt was:

This workflow demonstrates the dispatch-workflow safe output capability.
The agent can trigger the test-workflow using the test_workflow tool.

This was too passive - it described what the agent could do, but didn't tell it what it should do.

Changes Made

.github/workflows/test-dispatcher.md

• Added explicit instructions to call the dispatch_workflow safe output tool
• Added clear task description with specific action required
• Emphasized safe output usage with warning against file writing
• Structured prompt with sections for better clarity

The new prompt explicitly instructs:

**Your task**: Call the `dispatch_workflow` tool to trigger the `test-workflow` workflow.

**Important**: You MUST use the safe output tool - do NOT write to files or attempt other methods.

Expected Improvements

• ✅ Eliminates "No Safe Outputs Generated" errors by providing clear instructions
• ✅ Improves workflow reliability with explicit task definition
• ✅ Better agent guidance with structured prompt format
• ✅ Prevents alternative approaches that don't use safe outputs

Validation

Modified workflow file validated:

• ✅ Frontmatter structure intact
• ✅ Safe output configuration preserved
• ✅ Prompt structure improved with clear task definition
• ✅ No lock files included (will be compiled automatically)

Changes:
- Added clear instructions to call dispatch_workflow tool
- Emphasized using safe outputs instead of file writing
- Structured prompt with task and requirements
