feat: Add Scanner CI runner and related artifacts

- Implemented `run-scanner-ci.sh` to build and run tests for the Scanner solution with a warmed NuGet cache.
- Created `excititor-vex-traces.json` dashboard for monitoring Excititor VEX observations.
- Added Docker Compose configuration for the OTLP span sink in `docker-compose.spansink.yml`.
- Configured OpenTelemetry collector in `otel-spansink.yaml` to receive and process traces.
- Developed `run-spansink.sh` script to run the OTLP span sink for Excititor traces.
- Introduced `FileSystemRiskBundleObjectStore` for storing risk bundle artifacts in the filesystem.
- Built `RiskBundleBuilder` for creating risk bundles with associated metadata and providers.
- Established `RiskBundleJob` to execute the risk bundle creation and storage process.
- Defined models for risk bundle inputs, entries, and manifests in `RiskBundleModels.cs`.
- Implemented signing functionality for risk bundle manifests with `HmacRiskBundleManifestSigner`.
- Created unit tests for `RiskBundleBuilder`, `RiskBundleJob`, and signing functionality to ensure correctness.
- Added filesystem artifact reader tests to validate manifest parsing and artifact listing.
- Included test manifests for egress scenarios in the task runner tests.
- Developed timeline query service tests to verify tenant and event ID handling.

+# Advisory AI CI Runner Harness (DEVOPS-AIAI-31-001)
+
+Purpose: deterministic, offline-friendly CI harness for Advisory AI service/worker. Produces warmed-cache restore, build binlog, and TRX outputs for the core test suite so downstream sprints can validate without bespoke pipelines.
+
+Usage
+- From repo root run: `ops/devops/advisoryai-ci-runner/run-advisoryai-ci.sh`
+- Outputs land in `ops/devops/artifacts/advisoryai-ci/<UTC timestamp>/`:
+  - `build.binlog` (solution build)
+  - `tests/advisoryai.trx` (VSTest results)
+  - `summary.json` (paths + hashes + durations)
+
+Environment
+- Defaults: `DOTNET_CLI_TELEMETRY_OPTOUT=1`, `DOTNET_SKIP_FIRST_TIME_EXPERIENCE=1`, `NUGET_PACKAGES=$REPO/.nuget/packages`.
+- Sources default to `local-nugets` then the warmed cache; override via `NUGET_SOURCES` (semicolon-separated).
+- No external services required; tests are isolated/local.
+
+What it does
+1) Warm NuGet cache from `local-nugets/` into `$NUGET_PACKAGES` for air-gap parity.
+2) `dotnet restore` + `dotnet build` on `src/AdvisoryAI/StellaOps.AdvisoryAI.sln` with `/bl`.
+3) Run the AdvisoryAI test project (`__Tests/StellaOps.AdvisoryAI.Tests`) with TRX output; optional `TEST_FILTER` env narrows scope.
+4) Emit `summary.json` with artefact paths and SHA256s for reproducibility.
+
+Notes
+- Timestamped output folders keep ordering deterministic; consumers should sort lexicographically.
+- Use `TEST_FILTER="Name~Inference"` to target inference/monitoring-specific tests when iterating.
