feat: implement Ctrl+X to cut lines in commit view

Adds a keyboard shortcut (`Ctrl+X`) to the commit view that cuts the
current line and copies it to the system clipboard.

- Integrates `github.com/atotto/clipboard` for system access.
- Removes the active line from the textarea buffer.
- Records the change in the history buffer for undo support.
- Recalculates the cursor offset to maintain focus on the following
  line.

    D --> E[Remove line from buffer]
    E --> F[Push state to history]
    F --> G[Update cursor position]
    B -- Yes --> H[Ignore]
