feat: Add initial implementation of Vulnerability Resolver Jobs

- Created project for StellaOps.Scanner.Analyzers.Native.Tests with necessary dependencies.
- Documented roles and guidelines in AGENTS.md for Scheduler module.
- Implemented IResolverJobService interface and InMemoryResolverJobService for handling resolver jobs.
- Added ResolverBacklogNotifier and ResolverBacklogService for monitoring job metrics.
- Developed API endpoints for managing resolver jobs and retrieving metrics.
- Defined models for resolver job requests and responses.
- Integrated dependency injection for resolver job services.
- Implemented ImpactIndexSnapshot for persisting impact index data.
- Introduced SignalsScoringOptions for configurable scoring weights in reachability scoring.
- Added unit tests for ReachabilityScoringService and RuntimeFactsIngestionService.
- Created dotnet-filter.sh script to handle command-line arguments for dotnet.
- Established nuget-prime project for managing package downloads.

-- `GRAPH-SVC-30-00x` (in `src/Graph/StellaOps.Graph.Indexer/TASKS.md`) — stand up Graph Indexer pipeline, identity registry, snapshot exports.
+- `GRAPH-SVC-30-00x` (see `src/Graph/StellaOps.Graph.Indexer/TASKS.md`) — stand up Graph Indexer pipeline, identity registry, snapshot exports.
+- Active sprint: `docs/implplan/SPRINT_0141_0001_0001_graph_indexer.md` (Runtime & Signals 140.A) — clustering/centrality jobs, incremental/backfill pipeline, determinism tests, packaging.
 - `GRAPH-API-30-00x` — draft API planner/cost guard, streaming responses, and Authority scope integration.
 - `DOCS-GRAPH-24-003` & related backlog — author overview/API/query language docs; update this README again once those deliverables land.
 - Deployment/DevOps follow-ups (`DEVOPS-VEX-30-001`, `DEPLOY-VEX-30-001`) coordinate dashboards, load tests, and Helm/Compose overlays for the graph stack.
