Add workflow_call support with image-registry-namespace parameter

[simonrosenberg]

Overview

This PR adds workflow_call support to the benchmarks build workflow as part of the solution for OpenHands/software-agent-sdk#1249.

Purpose: Enable the software-agent-sdk repository to call this workflow directly instead of using dispatch + poll pattern, eliminating 80+ minutes of polling overhead.

Changes

workflow_call Trigger Added

workflow_call:
  inputs:
    dataset:
      description: 'Dataset name (e.g., princeton-nlp/SWE-bench_Verified)'
      required: true
      type: string
    split:
      description: 'Dataset split (e.g., test, dev)'
      required: true  
      type: string
    max-workers:
      description: 'Number of concurrent builds'
      required: false
      default: '32'
      type: string
    n-limit:
      description: 'Limit number of images to build'
      required: false
      default: ''''
      type: string
    sdk-commit:
      description: 'Software Agent SDK commit/ref to use'
      required: false
      default: ''''
      type: string
  outputs:
    images_built:
      description: 'Number of images successfully built'
      value: ${{ jobs.build-and-push.outputs.images_built }}
    sdk_commit:
      description: 'Actual SDK commit used for the build'
      value: ${{ jobs.build-and-push.outputs.sdk_commit }}
    image_base_name:
      description: 'Base name of the built images'
      value: ${{ jobs.build-and-push.outputs.image_base_name }}

Key Features

• ✅ Backwards Compatible: Existing workflow_dispatch and pull_request_target triggers preserved
• ✅ Proper Inputs: All parameters from dispatch workflow mirrored
• ✅ Output Values: Exposes build results for consumption by calling workflows
• ✅ No Behavior Changes: Logic unchanged, only trigger mechanism added

Related PRs

• Replace dispatch/poll with workflow_call for benchmarks orchestration software-agent-sdk#1255 - Uses this workflow_call capability
• OpenHands/evaluation (branch: openhands/workflow-call-support) - Similar changes for evaluation workflow

Benefits

When called from software-agent-sdk:

• Eliminates 80-iteration polling loop (80+ minutes maximum overhead)
• Reduces API calls from 40+ to 0 per evaluation run
• Enables direct data flow via outputs
• Creates explicit dependency chains visible in Actions UI

Testing Status

✅ Workflow syntax validated
✅ Compatible with existing triggers
✅ Outputs properly defined

⚠️ Cross-repository testing awaits admin configuration - see OpenHands/software-agent-sdk#1255 for details.
