Sort required fields in safe output custom job schemas for stable output

[Copilot]

The required array in safe output custom job schemas was non-deterministic due to Go map iteration order, causing unnecessary diffs in compiled workflows.

Changes

• pkg/workflow/safe_outputs_config_generation.go: Sort requiredFields alphabetically before adding to JSON schema
• pkg/workflow/safe_outputs_custom_job_tools_test.go: Add test verifying required array stability

Example

Before (random order):

{
  "inputSchema": {
    "required": ["zebra", "middle", "apple"]
  }
}

After (stable alphabetical order):

{
  "inputSchema": {
    "required": ["apple", "middle", "zebra"]
  }
}

This ensures workflow lock files have stable output across compilations when custom jobs define multiple required inputs.

Original prompt

The required array in the safe output custom jobs schema should be sorted to be stable.
