Fix dispatch-workflow missing workflow_files mapping in config

[Copilot]

Workflows using dispatch-workflow safe-output failed to trigger other workflows because the runtime config.json was missing the workflow_files map needed by the dispatch handler.

Root Cause

The workflow_files map (workflow name → file extension) was populated in generateFilteredToolsJSON() after generateSafeOutputsConfig() had already serialized config.json:

// mcp_setup_generator.go (before)
safeOutputConfig = generateSafeOutputsConfig(workflowData)  // workflow_files not yet populated
// ... later ...
filteredToolsJSON = generateFilteredToolsJSON(workflowData, ...)  // populates workflow_files

The runtime handler requires this mapping to construct workflow file paths:

// dispatch_workflow.cjs
const extension = workflowFiles[workflowName];  // undefined without the mapping
const workflowFile = `${workflowName}${extension}`;
await github.rest.actions.createWorkflowDispatch({ workflow_id: workflowFile, ... });

Changes

• pkg/workflow/safe_outputs_config_generation.go: Extract workflow file discovery logic into populateDispatchWorkflowFiles() that runs before config serialization
• pkg/workflow/mcp_setup_generator.go: Call populateDispatchWorkflowFiles() before generateSafeOutputsConfig()
• pkg/workflow/dispatch_workflow_test.go: Verify workflow_files is populated and included in config.json

Result

Config now includes the required mapping:

{
  "dispatch_workflow": {
    "workflow_files": { "test-workflow": ".yml" },
    "workflows": ["test-workflow"]
  }
}

Original prompt

Fix workflow not being able to trigger/run other workflows:
Max count: 1
✓ Loaded and initialized handler for: noop
Loaded 5 handler(s)
Collected 1 missing tool(s), 0 missing data item(s), and 0 noop message(s)
Processing 2 message(s) in order of appearance...
Processing message 1/2: missing_tool
✓ Recorded missing tool: workflow_dispatch or gh workflow run
Reason: Need to dispatch workflows but gh CLI is not authenticated. The workflows "add-name" and "add-emojis" require workflow_dispatch with a 'text' input parameter, but there's no available tool to trigger GitHub Actions workflows programmatically.
Alternatives: Workflows would need to be manually triggered through the GitHub UI, or a GitHub API token would need to be configured for gh CLI authentication.
✓ Message 1 (missing_tool) completed successfully
