"""Test bootstrap shared by every file under tests/.

- Adds the project root to `sys.path` so `import agent` works when pytest is
  invoked from the repo root.
- Provides a dummy `ANTHROPIC_API_KEY` and `SESSION_SECRET` so that pydantic
  settings can import without a real .env being present in CI.
