Parse review comments before trailing context blocks

When a send includes a review comment together with a preview annotation, terminal context, or element context, this appends the <review_comment> after the existing context blocks. UserTimelineRow still extracts preview annotations and terminal/element contexts only from the trailing end before UserMessageBody parses review comments, so those blocks no longer match and the transcript loses the preview/terminal/element cards or leaks their raw text. Strip review comments before those trailing extractors or update the display pipeline to handle this ordering.

Do not resurrect removed file comments

When a file preview comment is removed from the composer pill while this file editor stays mounted, the local lineAnnotations entry is never removed. On the next edit/remap, Pierre supplies that stale annotation in nextLineAnnotations, and this loop calls addReviewComment again, so the deleted comment reappears and can still be sent. Sync lineAnnotations with composer removals or filter remaps against the current draft comments before re-adding.
