Add ImageStitch node that concatenates images in four directions with optional borders and intelligent size handling. Features include optional second image input, configurable borders with color selection, automatic batch size matching, and dimension alignment via padding or resizing. Upstreamed from https://github.com/kijai/ComfyUI-KJNodes with enhancements for better error handling and comprehensive test coverage.

- Mock CUDA-dependent modules in tests to avoid CI failures on CPU-only runners - Fix ruff linting issues for code style compliance
Prevent CUDA initialization chain by mocking the nodes module at import time, which is cleaner than deep mocking of CUDA-specific functions.
- Remove unnecessary sys.path manipulation (pythonpath set in pytest.ini) - Remove metadata tests that test framework internals rather than functionality - Rename complex scenario test to be more descriptive of what it tests
- Change border_width/border_color to spacing_width/spacing_color in API - Update all tests to use spacing terminology - Update comments and variable names throughout - More accurately describes the gap/separator between images

There was a problem hiding this comment.
Looks good after the naming + default value changes, tested and works as expected.

Adds ImageStitch node for concatenating images in four directions with optional borders, size matching, and intelligent dimension handling. Supports optional second image input with passthrough when None, configurable borders with color selection, and automatic batch/channel alignment.
Upstreamed from https://github.com/kijai/ComfyUI-KJNodes with additional options for image border specification/control added.
