Pull request overview

Updates array membership checks across the codebase to maintain compatibility with the project’s NumPy requirement (numpy>=2.0.0) and ensure tests pass under NumPy 2.x.

Changes:

• Replaced deprecated/removed np.in1d usages with np.isin across analysis, I/O, and CLI utilities.
• Kept behavior consistent for boolean masks used in filtering and HEALPix alignment logic.
