Add tests for SBOM generation determinism across multiple formats

- Created `StellaOps.TestKit.Tests` project for unit tests related to determinism.
- Implemented `DeterminismManifestTests` to validate deterministic output for canonical bytes and strings, file read/write operations, and error handling for invalid schema versions.
- Added `SbomDeterminismTests` to ensure identical inputs produce consistent SBOMs across SPDX 3.0.1 and CycloneDX 1.6/1.7 formats, including parallel execution tests.
- Updated project references in `StellaOps.Integration.Determinism` to include the new determinism testing library.

+# Vuln Explorer — Using the Console (Md.XI draft)
+
+> Status: DRAFT (awaiting GRAP0101 domain model + console asset drop). Do not publish until hashes captured.
+
+## Scope
+- Walk through primary console workflows: search/filter, saved views, keyboard shortcuts, drill-down, evidence export.
+- Highlight identity/ABAC enforcement and tenant scoping in UI.
+- Keep all examples deterministic; attach payload/screenshot hashes to `docs/assets/vuln-explorer/SHA256SUMS`.
+
+## Prerequisites
+- Domain model from GRAP0101 (entities, identifiers) — needed for labels and field names.
+- UI/CLI asset drop (screenshots, payload samples) — requested, due 2025-12-09.
+- Ledger/observability context from `docs/modules/vuln-explorer/architecture.md` and Findings Ledger docs.
+
+## Workflows (to be filled with assets)
+1) Discover & filter findings (search, severity, reachability/VEX toggles).
+2) Keyboard shortcuts for navigation (list, detail, actions) — pending asset table.
+3) Saved views & deep links (shareable, ABAC-aware permalinks) — include hash-verified examples.
+4) Drill-down: finding detail → history → actions → attachments (token validation flow).
+5) Export: reports and offline bundles; note hash verification step.
+
+## Determinism & Offline Notes
+- All screenshots/payloads must be hashed; record in `docs/assets/vuln-explorer/SHA256SUMS`.
+- Use fixed fixture IDs and ordered outputs; avoid live endpoints.
+
+### Hash Capture Checklist (fill once assets arrive)
+- `assets/vuln-explorer/console-list.png` (list view with filters applied)
+- `assets/vuln-explorer/console-detail.png` (finding detail + history/actions panes)
+- `assets/vuln-explorer/console-shortcuts.md` (shortcut matrix payload)
+- `assets/vuln-explorer/console-saved-view.json` (saved view export)
+
+## Open Items before publish
+- Replace placeholders with GRAP0101-backed field names and identity labels.
+- Insert screenshot tables and payload snippets once assets arrive.
+- Add keyboard shortcut matrix and deep-link examples with hashes.
