Add chaos test GitHub Actions workflow

[moran-abilea]

This commit adds automated chaos testing infrastructure for ARMA:

• Daily scheduled runs at 6 AM Israel time (03:00 UTC) from Sun till Thu, only on Fri the test is longer
• Configurable test parameters (duration, rate, parties, shards)
• Sequential chaos pattern (stop/start components in order)
• Automatic result collection and artifact upload
• Support for both short and long-running tests

The workflow runs all ARMA components as separate processes on a single GitHub-hosted runner, with chaos testing that sequentially stops and restarts components to test system resilience.

Files added:

• .github/workflows/chaos-test.yml: Main workflow definition
• .github/workflows/chaosRunner/chaos-test.sh: Orchestration script
• .github/workflows/chaosRunner/start-arma-network.sh: Network startup
• .github/workflows/chaosRunner/chaos-runner.sh: Chaos implementation
• .github/workflows/chaosRunner/monitor-completion.sh: Test monitoring
• .github/workflows/chaosRunner/collect-results.sh: Result collection

Pull request overview

This PR introduces a scheduled/manual GitHub Actions workflow to run automated chaos testing for ARMA on a single GitHub-hosted runner, plus a related refactor that removes “primary signature” fields/methods from batch/BAF types and updates call sites/tests accordingly.

Changes:

• Add a new Chaos Test GitHub Actions workflow with scheduled and workflow_dispatch runs, artifact upload, and configurable parameters.
• Add bash runner scripts to generate configs, start the ARMA network, inject chaos (stop/start components), monitor completion, and collect results.
• Remove PrimarySignature from core Batch / BatchAttestationFragment interfaces and update constructors/call sites, mocks, and tests to match the new signatures.
