Update demo replay validation and testing documentation

- Modified the autodev state to reflect the current testing phase and details of the new `jetson-e2e` tests.
- Enhanced the "How to Test" documentation to provide clearer instructions on the demo replay validation process, including video and tlog alignment steps.
- Updated architectural documentation to include the new demo replay operator flow and its dependencies.
- Documented the removal of deprecated auto-sync features and clarified the operator-facing UI for replay validation.
- Added new entries in the dependencies table for upcoming tasks related to the demo replay flow.

These changes improve clarity and usability for operators and developers working with the demo replay system.

+# Step 3: CI/CD Pipeline
+
+**Role**: DevOps engineer
+**Goal**: Define the CI/CD pipeline with quality gates, security scanning, and multi-environment deployment.
+**Constraints**: Pipeline definition only — produce YAML specification, not implementation.
+
+## Steps
+
+1. Read `architecture.md` for tech stack and deployment targets
+2. Read `restrictions.md` for CI/CD constraints (cloud provider, registry, etc.)
+3. Research CI/CD best practices for the project's platform (GitHub Actions / Azure Pipelines)
+4. Define pipeline stages:
+
+| Stage | Trigger | Steps | Quality Gate |
+|-------|---------|-------|-------------|
+| **Lint** | Every push | Run linters per language (black, rustfmt, prettier, dotnet format) | Zero errors |
+| **Test** | Every push | Unit tests, blackbox tests, coverage report | 75%+ coverage (see `.cursor/rules/cursor-meta.mdc` Quality Thresholds) |
+| **Security** | Every push | Dependency audit, SAST scan (Semgrep/SonarQube), image scan (Trivy) | Zero critical/high CVEs |
+| **Build** | PR merge to dev | Build Docker images, tag with git SHA | Build succeeds |
+| **Push** | After build | Push to container registry | Push succeeds |
+| **Deploy Staging** | After push | Deploy to staging environment | Health checks pass |
+| **Smoke Tests** | After staging deploy | Run critical path tests against staging | All pass |
+| **Deploy Production** | Manual approval | Deploy to production | Health checks pass |
+
+5. Define caching strategy: dependency caches, Docker layer caches, build artifact caches
+6. Define parallelization: which stages can run concurrently
+7. Define notifications: build failures, deployment status, security alerts
+
