Add Policy DSL Validator, Schema Exporter, and Simulation Smoke tools

Browse Source 
- Implemented PolicyDslValidator with command-line options for strict mode and JSON output.
- Created PolicySchemaExporter to generate JSON schemas for policy-related models.
- Developed PolicySimulationSmoke tool to validate policy simulations against expected outcomes.
- Added project files and necessary dependencies for each tool.
- Ensured proper error handling and usage instructions across tools.

# Policy Samples
Curated fixtures used by CI smoke/determinism checks and example documentation.
| Scenario | Policy | Findings | Expected Diff | UI/CLI Diff Fixture |
|----------|--------|----------|---------------|---------------------|
| `baseline` | `docs/examples/policies/baseline.yaml` | `samples/policy/baseline/findings.json` | `samples/policy/baseline/diffs.json` | `samples/policy/simulations/baseline/diff.json` |
| `serverless` | `docs/examples/policies/serverless.yaml` | `samples/policy/serverless/findings.json` | `samples/policy/serverless/diffs.json` | `samples/policy/simulations/serverless/diff.json` |
| `internal-only` | `docs/examples/policies/internal-only.yaml` | `samples/policy/internal-only/findings.json` | `samples/policy/internal-only/diffs.json` | `samples/policy/simulations/internal-only/diff.json` |
Run the simulation harness locally:
```bash
dotnet run \
--project tools/PolicySimulationSmoke/PolicySimulationSmoke.csproj \
-- \
--scenario-root samples/policy/simulations \
--output out/policy-simulations
```
Then inspect `out/policy-simulations/policy-simulation-summary.json` for verdict changes.
