Subject: [PATCH] fix: use ProseMirror plugin instead of input rule for doc
 link auto-convert

Replace the InputRule (which only fires on sequential typing at the
cursor) with an appendTransaction plugin that scans text nodes on every
transaction. This handles all editing patterns: typing brackets first
then filling in the target, pasting, etc.
