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.

+> **Applicability** — the table columns `Pinned Mode/Config` and `API Capability Evidence` apply only to technical-component runs (per SKILL.md → Research Output Class). For non-technical research outputs (concept comparison, market/policy report, investigation answer), this Architecture section may be replaced with a comparison/analysis section that does not use these columns; or the columns may be marked `N/A` per row when the row describes a non-technical "component" (a process, a policy, an organizational construct). For mixed runs, fill the columns only on rows that describe libraries/SDKs/frameworks/services/protocols/data formats/algorithms.

+
+| Solution | Tools | Pinned Mode/Config | Advantages | Limitations | Requirements | Security | Cost | API Capability Evidence | Fit |
+|----------|-------|--------------------|-----------|-------------|-------------|----------|------|-------------------------|-----|
+| [Option 1] | [lib/platform] | [exact mode/config used: inputs, outputs, runtime] | [pros] | [cons] | [intrinsic requirements] | [security] | [cost] | MVE: [link to MVE block]; docs: [Source #] | [Selected / Rejected / Experimental only / Needs user decision — cite exact-fit evidence and disqualifiers] |
+| [Option 2] | [lib/platform] | [exact mode/config used] | [pros] | [cons] | [intrinsic requirements] | [security] | [cost] | MVE: [link]; docs: [Source #] | [Selected / Rejected / Experimental only / Needs user decision] |
+
+**Exact-fit evidence**:
+- Project constraints checked: [inputs/outputs, operating context, lifecycle, NFRs, acceptance criteria]
+- Evidence: [Fact # / Source #]
+- Disqualifiers: [none or list]
+- Restrictions × Candidate-Modes sub-matrix: see `06_component_fit_matrix.md` (or `06_component_fit_matrix/` if split) § <Candidate Name>
+- API capability gates: ✅ MVE saved / ⚠️ partial — see disqualifiers / ❌ no MVE — candidate is Experimental only or Rejected

+[Repeat per component]
+
+## Testing Strategy
+
+### Integration / Functional Tests
+- [Test 1]
+- [Test 2]
+
+### Non-Functional Tests
+- [Performance test 1]
+- [Security test 1]
