Description

buildShareFromSession in share.go:183-214 iterates s.Files and collects per-file comments, but never includes s.reviewComments. The CLI crit share path (via loadCommentsFromCritJSON) does include them.

This means review-level (non-file-scoped) comments are silently dropped when sharing from the browser's Share button during a live session.

Steps to reproduce

1. Start a review with crit
2. Add a review-level comment (not anchored to a file)
3. Click Share in the browser
4. View the shared review — review-level comment is missing

Suggested fix

After the file loop in buildShareFromSession, iterate s.reviewComments and add them as shareComment entries with Scope: "review".
