docs(readme): add parallel WAA evaluation, fix build badge

[abrichr]

Summary

• Fix broken build status badge (referenced publish.yml but file is release.yml)
• Add prominent "Parallel WAA Benchmark Evaluation" section near the top highlighting the new v0.3.0 feature
• Add detailed "WAA Benchmark Workflow" section (refactor(cli): minimal WAA CLI with vanilla image support #14) with complete setup instructions

Changes

Badge Fix

The build status badge was showing a broken image because it referenced a non-existent workflow file.

New Documentation

Near the top (high visibility):

• Quick start commands for pool-create, pool-wait, pool-run
• Performance estimates table (1 worker vs 5 vs 10)
• Key features summary

Detailed workflow section (#14):

• Prerequisites (Azure CLI, API keys, quota)
• Single VM workflow for quick testing
• Parallel pool workflow for full evaluations
• VNC access instructions for viewing Windows VMs
• Architecture diagram
• Cost estimates table

Test plan

• Verify badge displays correctly on GitHub
• Verify anchor link from top section works
• Review documentation accuracy

Self-Review

✅ What's Good

1. Badge fix is correct - publish.yml → release.yml matches the actual workflow file
2. Prominent placement - New parallel WAA section at top gives immediate visibility to the key new feature
3. Complete workflow documentation - Section 14 covers prerequisites, single VM, parallel pool, VNC access, architecture, and costs
4. Accurate commands - All CLI commands match the actual implementation
5. Helpful performance table - Gives users clear expectations for time savings

⚠️ Suggestions for Improvement

1. Anchor placement - The <a id="waa-benchmark-workflow"></a> is after the heading. Move it before for proper anchor behavior:

   <a id="waa-benchmark-workflow"></a>
   ## 14. WAA Benchmark Workflow

2. Missing pool-delete command - Section 14.3 references pool-delete -y but this command may not exist yet (need to verify). Should either:

   • Add the command to CLI if missing
   • Change to existing cleanup approach

3. VNC tunnel ports - The manual SSH tunnel examples show hardcoded IPs (<worker-0-ip>). Could mention how to get IPs:

   # Get worker IPs from pool-status
   uv run python -m openadapt_ml.benchmarks.cli pool-status

4. Cost estimate accuracy - The $0.38/hr is approximate. Consider adding "prices vary by region" caveat.

5. Missing error handling docs - No mention of what to do if pool-create fails mid-way (use pool-cleanup?)

🔍 Verification Needed

• Confirm pool-delete command exists
• Test anchor link from top section actually navigates to section 14
• Verify badge now renders correctly on GitHub

Verdict

Approve with minor suggestions - The core documentation is valuable and accurate. The suggestions above are enhancements, not blockers.

Fixed in Latest Push (5d3f4f8)

Addressed the self-review feedback:

• ✅ Anchor placement - Moved <a id="waa-benchmark-workflow"></a> before the heading
• ✅ Command name - Changed pool-delete -y → pool-cleanup (the actual command)
• ✅ Worker IPs - Added pool-status example before SSH tunnel commands
• ✅ Price caveat - Added "Prices vary by Azure region" note

Ready for final review.
