The upstream TipTap Code extension input rule regex /(^|[^`])`([^`]+)`(?!`)$/
uses a capture group (^|[^`]) that includes the character preceding the
opening backtick in the full match. When markInputRule processes this,
it deletes everything from the match start to the code content, which
removes that preceding character along with the backtick delimiters.
For example, typing foo(`bar` would result in foo`bar` (formatted)
instead of the expected foo(`bar` (formatted) — the ( is lost.
Fix: disable the built-in Code extension from StarterKit and register it
separately with a corrected regex that uses a lookbehind assertion
(?:^|(?<=[^`])) instead of a capture group. The lookbehind asserts the
preceding character without including it in the match, so markInputRule
only deletes the backtick delimiters.
Functionally tested on Firefox and Chrome.

* 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.
