Description
Adds a new Python migration guide for moving from Celery to Hatchet.
The guide focuses on practical migration steps for an existing Celery project, including dependency and configuration changes, task definitions, task invocation, workers, retries, timeouts, delayed and periodic execution, Celery Canvas patterns, result handling, routing, lifecycle hooks, cancellation, priority, testing, and final cleanup.
This also adds supporting Python migration snippets under
sdks/python/examples/migration_guides/celery.py, which are referenced from the MDX guide and generated into the docs snippet system.Type of change
