Analyze CI test failures and recommend fixes

[Copilot]

Investigation of CI workflow failures to identify root causes and recommend fixes.

Analysis Completed

• Reviewed .github/workflows/ci.yml structure covering lint, test (matrix), notebook imports, dependency check, build, and docs jobs
• Identified CI workflow ID (212672334) for further log retrieval
• Mapped test matrix: Ubuntu/Windows/macOS × Python 3.10-3.12

Investigation Status

Analysis was partially completed. To finalize:

1. Retrieve recent workflow run logs via GitHub Actions API
2. Identify specific failing jobs from run history
3. Implement targeted fixes based on error messages

Common Failure Patterns to Check

• Lint: ruff/black violations in src/ or tests/
• Windows: libvips installation from build-win64-mxe releases
• Notebook imports: Missing Kreg, Kview, Kstitch module dependencies
• Dependency check: check_dependencies() validation failures
