feat(workflow): auto-detect committed baseline in agentops-pr templates

[placerda]

Closes #155.

The PR-gate workflow templates emitted by �gentops workflow generate did not pass --baseline to �gentops eval run, even though docs/tutorial-baseline-comparison.md Section 4 promises:

The �gentops-pr.yml workflow shipped by �gentops workflow generate already supports this — drop a baseline file in your repo (e.g. .agentops/baseline/results.json) and add this step: ...

Both the GitHub Actions and Azure DevOps PR templates now wrap the eval invocation with a small bash guard that auto-detects .agentops/baseline/results.json:

BASELINE_ARG=""
if [ -f .agentops/baseline/results.json ]; then
  BASELINE_ARG="--baseline .agentops/baseline/results.json"
fi
agentops eval run --config <cfg> $BASELINE_ARG

When the file is present, the eval step compares against it. When absent, BASELINE_ARG stays empty and the bash invocation is byte-equivalent to the prior behaviour. Deploy templates (dev/qa/prod) are intentionally untouched.

Implementation

• _eval_substitutions, _github_eval_substitutions, _ado_eval_substitutions now take a kind kwarg.
• Only kind == 'pr' injects the baseline-detection bash.
• Indentation is handled by two small helpers so the YAML stays valid for both the GH Actions run: | block and the ADO AzureCLI@2 inlineScript.

Tests

Added to tests/unit/test_cicd.py:

• test_pr_template_autodetects_committed_baseline
• test_deploy_templates_do_not_inject_baseline_autodetect
• test_azure_devops_pr_template_autodetects_committed_baseline
• test_azure_devops_deploy_templates_do_not_inject_baseline_autodetect

Validation

python -m pytest tests/unit -x -q — 946 passed, 1 skipped.
