Make terminalbench work with CI pipeline

[neubig]

We have a CI pipeline spread across:
OpenHands/software-agent-sdk
OpenHands/benchmarks
OpenHands/evaluation

Add the terminalbench benchmark to all of these repos as necessary, and trigger a run on software-agent-sdk CI to make sure that this works. If it doesn't work with 5 examples, debug and figure out why.

Final summary for issue #490:

Status

• Terminal-Bench was wired into all three repos as requested:
  • OpenHands/benchmarks
  • OpenHands/evaluation
  • OpenHands/software-agent-sdk
• Changes were kept focused on Terminal-Bench CI/eval integration.
• Changes were committed, pushed, and PRs opened.
• A 5-example Terminal-Bench smoke run was triggered from software-agent-sdk CI.
• The cross-repo dispatch path worked: the SDK workflow successfully launched the downstream evaluation workflow.

Concise summary of what changed

• In benchmarks, I fixed the Terminal-Bench Harbor defaults for CI:

  • corrected the dataset to terminal-bench@2.0
  • added --n-limit support so CI can run a 5-task smoke test
  • updated docs/install guidance (harbor, not harbor-bench)
  • added regression coverage for the new CLI behavior

• In evaluation, I added Terminal-Bench execution support:

  • exposed terminalbench in workflow inputs
  • added a dedicated run_terminalbench.sh
  • wired it into run_eval.sh, Helm values, and the Kubernetes job template
  • added push-to-index support for Terminal-Bench archives/counts
  • added tests for the new benchmark mapping/count behavior

• In software-agent-sdk, I exposed terminalbench in the manual run-eval workflow and updated the internal run-eval documentation.

Important debugging result

I initially tried adding harbor as a direct dependency in the benchmarks repo, but that caused dependency resolution conflicts with commit0. I reverted that approach and instead made the evaluation runner install harbor==0.1.45 on demand. That kept the benchmarks environment buildable while still enabling Terminal-Bench CI runs.

Validation performed

• make build
• uv run pre-commit run --files ...
• uv run pytest tests/test_terminalbench.py
• python3 -m unittest tests/test_push_to_index_from_archive.py
• shell syntax checks for the evaluation scripts
