Greptile Summary

This PR bumps the appwrite CLI formula to 19.2.0, updates all four platform SHA256 hashes, and makes two code improvements: the install method is refactored from an early-return pattern to a clean if/else, and generate_completions_from_executable is added (along with a corresponding test) so that shell completions are installed for all supported shells.

Confidence Score: 5/5

This PR is safe to merge — it is a straightforward version bump with valid SHA256 hashes and clean refactoring.

All SHA256 hashes are well-formed 64-character hex strings, the version bump is consistent across URL references (which interpolate #{version}), the install method refactoring is logically equivalent and cleaner, and the new completion generation is placed correctly outside the if/else so it runs in both head and release builds.

No files require special attention.
