Greptile Summary

This documentation-only PR corrects several spelling and grammar issues in the README.

• Improves the development-status and release-note wording.
• Clarifies the device compatibility warning.
• Leaves one misspelling in the compatibility instructions.

Confidence Score: 4/5

The PR appears safe to merge, though the remaining “wether” misspelling should be corrected.

The documentation changes do not affect runtime behavior, and the only identified issue is a non-blocking spelling mistake in the updated warning.
