Subject: [PATCH 01/17] feat: add Mermaid workflow diagram generation and
 GitHub integration testing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add new mermaid/workflow-diagram model for generating visual workflow diagrams
- Create comprehensive GitHub workflow for integration testing
- Test artifact passing, dependencies, and cross-model references
- Generate Mermaid diagrams from workflow execution data with color-coded status
- Upload workflow artifacts and diagrams to GitHub Actions
- Validate shell command dependencies, expression evaluation, and error handling

Subject: [PATCH 02/17] remove lint and format check from integration test
 workflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The existing CI workflow already handles linting and formatting checks.
The integration test workflow should focus on end-to-end functionality testing.

The swamp repo init command does not accept a --models-dir option.
Models directory is configured via .swamp.yaml or defaults to extensions/models.

Subject: [PATCH 15/17] fix: correct error handling test logic for failing
 models
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Swamp returns success when executing models even if the model's shell
command fails. The failure is captured in the model's exitCode attribute.
Updated test to check model.data.attributes.exitCode instead of expecting
the swamp command itself to fail.
