Adds opt-in flag to exclude the dags/ directory prefix from DAG bundles. This is needed for Airflow 3.x where sys.path includes the bundle root, causing imports from shared modules in dags/ to fail. Usage: astro deploy --dags --no-dags-base-dir Fixes astronomer#1985

There was a problem hiding this comment.
This is really just testing that the negation operator still works but I guess you can never be too careful

Summary
--no-dags-base-dirflag toastro deploy --dagsfor Airflow 3.x compatibilitydags/directory prefix (existing behavior)--no-dags-base-dir, DAG files are placed at the bundle rootUsage
Context
Airflow 3 changed the DAG processor to add the bundle root to
sys.pathinstead of thedags/folder. This caused imports from shared modules in thedags/directory to fail for DAG-only deploys.This flag gives users explicit control over the bundle layout without changing default behavior.
Fixes #1985
