Fixed the green checkmark remaining on screen after all writing suggestions are resolved. It now disappears after one second and stays hidden when scrolling or resizing. The numbered badge returns when new suggestions are detected.

Added undo for the last correction, keyboard-accessible suggestion controls, “Ignore for session,” and locally stored personal typo-to-correction pairs.
Typo.js is now an exact, unmodified copy of official npm release 1.3.2. All spelling and writing checks remain local; no writing is transmitted or logged.

Fixed a suggestion message that could remain visible after correcting text or closing an email
editor.
Messages can now be dismissed with the close button, the badge, Escape, or by leaving/
removing the editor.
