Update expect.txt and improve code comments

Updated `expect.txt` to add new terms (e.g., `debouncer`, `onnx`, `PowerDisplay`) and remove outdated ones across multiple sections.

Refined comments in the codebase for grammatical accuracy, clarity, and consistency:
- Corrected verb forms (e.g., "fallback" to "fall back").
- Fixed spelling (e.g., "re-entrant" to "reentrant").
- Improved punctuation for better readability.

These changes enhance code maintainability and ensure up-to-date terminology.
