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.

+# AGENTS · docs/implplan (Coordination Sprints)
+
+## Purpose & Scope
+- Working directory: `docs/implplan` (sprint planning/coordination docs only). Cross-module edits must be explicitly noted in the relevant sprint’s Decisons & Risks.
+- Roles supported here: project manager, product manager, implementer (doc maintainer). No code changes are performed in this directory; focus on sprint plans, status, and cross-guild coordination.
+
+## Required Reading (treat as read before DOING)
+- `docs/README.md`
+- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
+- `docs/modules/platform/architecture-overview.md`
+- `docs/implplan` sprint template rules (see Section “Naming & Structure” below)
+- Any sprint-specific upstream docs linked from the current sprint file (e.g., crypto audit, replay runbooks, module architecture dossiers referenced in Dependencies/Prereqs sections)
+
+## Naming & Structure
+- Sprint filename format: `SPRINT_<IMPLID>_<BATCHID>_<SPRINTID>_<topic>.md` (see global charter §4.2). Normalize existing files to this format while preserving content and log the rename in Execution Log.
+- Internal template (required sections): Topic & Scope, Dependencies & Concurrency, Documentation Prerequisites, Delivery Tracker, Wave Coordination (if multi-wave), Wave Detail Snapshots, Interlocks, Upcoming Checkpoints, Action Tracker, Decisions & Risks (incl. risk table), Execution Log.
+- Status flow: `TODO → DOING → DONE/BLOCKED`. Flip status only when evidence is captured in the sprint doc.
+
+## Determinism & Metadata
+- Use UTC dates (`YYYY-MM-DD`) and include timezone labels for meetings if relevant.
+- Keep tables ordered deterministically (by task ID or due date). Avoid ad-hoc reshuffling.
+- When blocking, state the concrete dependency/document name and expected next signal/date.
+
+## Documentation Rules
+- For any design/advisory/platform decision surfaced here, update the canonical doc under `docs/**` (architecture, ADR, product advisory, etc.) and link it from Decisions & Risks.
+- Archival: completed tasks should flow to `docs/implplan/archived/tasks.md` as per sprint guidance.
+- Avoid external URLs unless already present; prefer relative doc links.
+
+## Cross-Module Coordination
+- Respect each module’s AGENTS.md when touching module-specific sprint entries; do not change module instructions from here.
+- If a required module AGENTS.md is missing/outdated, mark the related task BLOCKED in that module’s sprint and note it in Decisions & Risks here.
+
+## Ready-to-Start Checklist (per change)
+- Confirm template compliance of the sprint file you’ll edit.
+- Verify statuses reflect current reality before adding new actions.
+- Add Execution Log line summarizing what changed, with date and role.
+
+## Testing / Validation
+- No automated tests; validate by: (1) template conformance, (2) table integrity (columns align), (3) links resolve locally.
+
+## Contacts & Stand-ups
+- Follow sprint-specific checkpoint dates listed in “Upcoming Checkpoints”. Escalations are logged in Decisions & Risks, not via chat.
