* fix: resolve keystroke input being swallowed after link in Firefox
In Firefox, when the cursor is at the right boundary of a link mark,
contenteditable inserts new text inside the <a> element. ProseMirror
then rejects the DOM mutation because the link mark has inclusive: false,
causing keystrokes to be silently swallowed. Unlike Chrome, Firefox also
does not fire ProseMirror's handleTextInput callback in this state.
This adds a ProseMirror plugin that intercepts printable character
keydowns at link mark boundaries and programmatically inserts the text
without the link mark, bypassing Firefox's native contenteditable
behavior entirely.

* fix: resolve keystroke input being swallowed before a link in Firefox
Extend the linkBoundaryInput plugin to also handle the left boundary
of links, where the cursor is just before a link (e.g. at the start
of a line). Firefox inserts text inside the <a> element in this case
too, causing ProseMirror to reject the mutation.
