Fix line-based editing behavior for cut and duplicate commands

- Cut to temp buffer:
  - Respect selections by expanding to full line boundaries
  - Normalize end iterator to include full line + newline
  - Ensure consistent newline handling for last line
  - Preserve cursor position after delete
  - Prevent line merging when accumulating cut buffer

- Duplicate line:
  - Simplify logic using line-based iter APIs
  - Fix incorrect selection handling and off-by-one issues
  - Ensure full-line duplication for both selection and cursor cases
  - Correct cursor/selection restoration after duplication
