Add unit tests for Router configuration and transport layers

- Implemented tests for RouterConfig, RoutingOptions, StaticInstanceConfig, and RouterConfigOptions to ensure default values are set correctly.
- Added tests for RouterConfigProvider to validate configurations and ensure defaults are returned when no file is specified.
- Created tests for ConfigValidationResult to check success and error scenarios.
- Developed tests for ServiceCollectionExtensions to verify service registration for RouterConfig.
- Introduced UdpTransportTests to validate serialization, connection, request-response, and error handling in UDP transport.
- Added scripts for signing authority gaps and hashing DevPortal SDK snippets.

+# Console Forensics (stub)
+
+> Status: BLOCKED awaiting timeline/evidence viewer assets and payloads from Console Guild. Follow this outline when assets arrive.
+
+## Scope
+- Timeline explorer, evidence viewer, attestation verifier flows.
+- Imposed rule banner and offline-friendly walkthroughs.
+- Troubleshooting section with deterministic repro steps.
+
+## Pending inputs
+- Deterministic captures (command-rendered or approved screenshots) for timeline and evidence viewer states.
+- Sample NDJSON/JSON payloads for evidence/attestation, with hashes.
+- Error taxonomy and retry/backoff guidance for user-facing errors.
+
+## Determinism checklist
+- Hash all captures/payloads in co-located `SHA256SUMS` when provided.
+- Use UTC timestamps and stable ordering in tables and examples.
+
+## Outline
+1. Overview + banner
+2. Timeline explorer walkthrough (filters, drilldowns)
+3. Evidence viewer (attestations, signatures, DSSE bundle) examples
+4. Attestation verifier steps and expected outputs
+5. Troubleshooting + error taxonomy
+6. Offline/air-gap operation steps
+7. Verification (hash check + replay commands)
