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.

+# Dependencies Table Template
+
+Use this template after cross-task verification. Save as `TASKS_DIR/_dependencies_table.md`.

+# Dependencies Table
+
+**Date**: [YYYY-MM-DD]
+**Total Tasks**: [N]
+**Total Complexity Points**: [N]
+
+| Task | Name | Complexity | Dependencies | Epic |
+|------|------|-----------|-------------|------|
+| [TRACKER-ID] | initial_structure | [points] | None | [EPIC-ID] |
+| [TRACKER-ID] | [short_name] | [points] | [TRACKER-ID] | [EPIC-ID] |

+## Guidelines
+
+- Every task from TASKS_DIR must appear in this table
+- Dependencies column lists tracker IDs (e.g., "AZ-43, AZ-44") or "None"
+- No circular dependencies allowed
+- Tasks should be listed in recommended execution order
+- The `/implement` skill reads this table to compute dependency-aware batches; task execution remains sequential
