  This series adds enhanced editing features to the U-Boot command line,
including multi-level undo/redo, yank/paste, word navigation, and
multiline editing support for the expo textedit widget.

Key features:
- Multi-level undo (Ctrl+Z) and redo (Ctrl+Shift+Z) with configurable
  depth via CONFIG_CMDLINE_UNDO_COUNT
- Yank/paste killed text with Ctrl+Y
- Word navigation with Ctrl+Left/Right arrows
- Home/End key support in sandbox SDL console
- Multiline editing mode where Ctrl+K kills to end of line (not buffer)
  and Home/End navigate within the current line

The series also includes test infrastructure improvements, fixes a memory
leak in expo text object destruction, and fixes a buildman bug with
merge_config.sh path resolution when using work directories.
