Improve Error Strategy for Specific Workflow Processes

[anilthanki]

Processes like run_tsne, run_umap, find_markers, and find_clusters currently use errorStrategy 'ignore', allowing them to fail without interrupting the workflow.

A more robust error-handling strategy should be implemented to improve reliability and ensure failures are properly logged and managed.

Tasks:

• Review current error strategy.
• Propose and implement a better alternative.
• Test and validate the new approach.

This also leads to an inability to retry.
