Ci/argo build then backtest

[bxvtr]

Summary

Introduce CI workflow that builds the Docker image via Argo (Kaniko) and optionally triggers the Argo backtest workflow using the built image tag.

Motivation

Automate the full pipeline from image build to backtest execution to ensure reproducible, commit-based testing directly within Kubernetes.

Type of Change

• Bug fix
• New feature
• Performance improvement
• Refactor
• Documentation
• Breaking change

Technical Details

• Added GitHub Actions workflow to:

  • Submit Argo build workflow
  • Wait for successful completion
  • Submit backtest workflow conditionally

• Image tagged with commit SHA for deterministic execution.

• Backtest workflow consumes the exact built image.

• Switched scratch storage to dynamic PVC provisioning via microk8s-hostpath.

Determinism & Reproducibility

• Change preserves deterministic behavior
• Tests confirm reproducibility
• No hidden state introduced

Image tag is pinned to GITHUB_SHA, ensuring deterministic backtest runs.

Performance Impact

• No measurable impact

Pipeline orchestration only; no runtime performance changes.

Tests

• Unit tests added/updated
• Integration tests added/updated
• Existing tests pass

Backtest execution validated in dev namespace.

Breaking Changes

None. Existing workflows remain compatible.

Checklist

• Code follows project style guidelines
• Self-review completed
• Documentation updated (if needed)
