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)

+# Console Observability (stub)
+
+> Status: BLOCKED awaiting Observability Hub widget captures + deterministic sample payload hashes from Console Guild. This stub locks structure and checklist; replace placeholders once assets arrive.
+
+## Scope
+- Observability Hub widgets (traces, logs, metrics) for runtime/signals and graph overlays.
+- Accessibility and imposed rule banner.
+- Offline parity: all captures and sample payloads must be stored locally with SHA256 hashes.
+
+## Pending inputs (must be supplied before publish)
+- Widget screenshots or command-rendered outputs (deterministic capture).
+- Sample payloads (JSON/NDJSON) with hash list.
+- Alert rules/thresholds and dashboard import JSON.
+
+## Determinism checklist
+- Record all hashes in a `SHA256SUMS` alongside captures once provided.
+- Use UTC ISO-8601 timestamps and stable sort order for tables/output snippets.
+- Avoid external links; refer to local assets only.
+
+## Outline (to fill when unblocked)
+1. Overview and imposed rule banner
+2. Widget catalog (cards/tables) with captions
+3. Search/filter examples (logs, traces) with sample payloads
+4. Dashboards and alert thresholds (import JSON path)
+5. Accessibility and keyboard shortcuts
+6. Offline/air-gap import steps
+7. Verification steps (hash check + replay)
