* fix: cursor jumps to end of text when editing a comment
When editing a comment mid-text, the cursor would jump to the end after
every keystroke, making it impossible to insert text at any position
other than the end.
Root cause: on each keystroke, the comment editor's onUpdate callback
updated parent state (setContent), which changed the defaultContent prop
passed back to CommentEditor. A useEffect watching defaultContent then
called commentEditor.commands.setContent(), which reset the entire
editor content and moved the cursor to the end.
Fix:
- Store in-progress edits in a ref instead of state to avoid triggering
React re-renders and the prop->effect->setContent cascade
- Read from the ref when saving the comment
- Sync the ref back into state after a successful save so the read-only
view updates immediately
- Guard the setContent useEffect to only run for read-only editors, so
websocket-driven updates from other browsers still work
Fixes#1791
Functionally tested on Firefox and Chrome: mid-text editing, saving,
cross-browser live updates via websocket.
