feat: add nightly load test

[vbhattaccmu]

Summary

Adds a nightly GitHub Actions workflow that runs once per day against develop, builds Bor and Heimdall v2 Docker images from develop, starts the existing Kurtosis Polygon PoS E2E network, runs a polycli loadtest, and publishes load-test statistics as both a job summary and retained artifact.

Executed tests

• Validated .github/workflows/nightly-load-tests.yml with actionlint.
• Parsed the workflow YAML successfully.
• Checked for trailing whitespace.
• Did not run the full Kurtosis workflow locally; it is intended to run in CI.

Rollout notes

CI-only change. Not consensus-affecting, no protocol or runtime behavior changes, no coordinated upgrade required. The temporary branch push trigger is only for CI validation and should be removed before merging if the final workflow should run only daily and via manual dispatch.

Pull request overview

Adds a new nightly GitHub Actions workflow to exercise Bor + Heimdall v2 via the existing Kurtosis Polygon PoS E2E network and run a polycli loadtest, publishing metrics to the job summary and an artifact. This fits into the repo’s CI/automation surface as a scheduled performance/regression signal for develop.

Changes:

• Introduces a scheduled + manual workflow to build Bor/Heimdall v2 images from develop and run Kurtosis.
• Runs polycli loadtest, captures metadata/summary JSON + logs, and uploads results as an artifact.
• Collects network diagnostics/state dump automatically on load-test failure.
