Behavior test run posts comment with "Integration Tests Results" title

Problem

When a release PR is tagged with the behavior-test label, the Run Integration Tests workflow runs the behavior test suite and posts a results comment on the PR. However, that comment uses the title:

🧪 Integration Tests Results

…which is the same title used by the regular integration test run. This makes it hard to tell the two result comments apart on a PR.

For context, see this example comment from a behavior-test run: https://github.com/OpenHands/software-agent-sdk/pull/4942#issuecomment-5624939445 (the linked run is https://github.com/OpenHands/software-agent-sdk/actions/runs/34524458141).

The corresponding release checkpoints are:

• Integration tests pass (tagged with integration-test)
• Behavior tests pass (tagged with behavior-test)
• Example tests pass (tagged with test-examples)

Expected behavior

When the run is a behavior test run, the results comment should be titled:

🧪 Behavior Tests Results

Regular integration test runs should keep the existing # 🧪 Integration Tests Results title.

Root cause

The title is hardcoded as # 🧪 Integration Tests Results in tests/integration/utils/generate_markdown_report.py (generate_markdown_report), so it is identical regardless of which test suite actually ran. The consolidated results already carry per-instance test_type (integration / behavior / condenser), so the correct title can be derived from the data.

This issue was created by an AI agent (OpenHands) on behalf of @juanmichelini.

Start in tests/integration/utils/generate_markdown_report.py at generate_markdown_report and inspect how the consolidated results expose each instance's test_type. Update the generated title so behavior runs use “Behavior Tests Results” while regular integration runs retain “Integration Tests Results”; done means the two result comments are distinguishable.
