feat: Initialize Zastava Webhook service with TLS and Authority authentication

- Added Program.cs to set up the web application with Serilog for logging, health check endpoints, and a placeholder admission endpoint.
- Configured Kestrel server to use TLS 1.3 and handle client certificates appropriately.
- Created StellaOps.Zastava.Webhook.csproj with necessary dependencies including Serilog and Polly.
- Documented tasks in TASKS.md for the Zastava Webhook project, outlining current work and exit criteria for each task.

+# NPM Monorepo Fixture
+
+This fixture represents a trimmed monorepo layout used by the analyzer microbench. It contains four packages under `node_modules/` with realistic metadata and dependency edges.
+
+- `@stella/core` depends on `lodash`.
+- `@stella/web` depends on `@stella/core` and `rxjs`.
+- Third-party packages expose standard `name`, `version`, and `license` fields.
+
+The files are intentionally small so that the bench harness focuses on directory traversal and metadata parsing overhead.
