Add GitHub Actions workflow for dbt integration tests

Add CI workflow that:
1. Installs Python dependencies and Feast
2. Installs dbt-core and dbt-duckdb
3. Runs dbt build to generate manifest.json
4. Sets up Feast project with SQLite
5. Tests feast dbt import command
6. Verifies Feast objects were created
7. Runs pytest integration tests

Workflow runs on PRs that modify:
- dbt integration code (feast/dbt/**)
- dbt integration tests (tests/integration/dbt/**)
- The workflow file itself

Tests run on Python 3.11 and 3.12 to ensure compatibility.
