Add unit tests and logging infrastructure for InMemory and RabbitMQ transports

- Implemented RecordingLogger and RecordingLoggerFactory for capturing log entries in tests.
- Added unit tests for InMemoryChannel, covering constructor behavior, property assignments, channel communication, and disposal.
- Created InMemoryTransportOptionsTests to validate default values and customizable options for InMemory transport.
- Developed RabbitMqFrameProtocolTests to ensure correct parsing and property creation for RabbitMQ frames.
- Added RabbitMqTransportOptionsTests to verify default settings and customization options for RabbitMQ transport.
- Updated project files for testing libraries and dependencies.

+## 11 · TP Gap Remediation (2025-12)
+
+- **Signed registry record (TP7):** Every pack version stores DSSE envelopes for bundle + attestation, SBOM path, and revocation list reference. Imports fail-closed when signatures or revocation proofs are missing.
+- **Offline bundle schema (TP8):** Registry exports offline artefacts that must satisfy `docs/task-packs/packs-offline-bundle.schema.json`; publish pipeline invokes `scripts/packs/verify_offline_bundle.py --require-dsse` before promotion.
+- **Hash ledger (TP1/TP2):** Publish step writes `hashes[]` (sha256) for manifest, canonical plan, `inputs.lock`, approvals ledger, SBOM, and revocations; digests surface in audit events and `digestmap.json`.
+- **Sandbox + quotas (TP6):** Registry metadata carries `sandbox.mode`, explicit egress allowlists, CPU/memory limits, and quota seconds; Task Runner refuses packs missing these fields.
+- **SLO + alerting (TP9):** Pack metadata includes SLOs (`runP95Seconds`, `approvalP95Seconds`, `maxQueueDepth`); registry emits metrics/alerts when declared SLOs are exceeded during publish/import flows.
+- **Fail-closed imports (TP10):** Import/mirror paths abort when DSSE, hash entries, or revocation files are absent or stale, returning actionable error codes for CLI/Task Runner.
