Subject: [PATCH 1/3] feat(cloud-agent): send saved diff reviews to chats

- Add saved-diff line/range comments, cross-file drafts, and one batched Send review to agent action.
- Preserve immutable reviewed context and explicit stale-review handling across file and chat switches.
- Pin and authorize the destination worktree/chat, retaining the same message identity for uncertain retries.

Restacked onto latest main and squashed to one commit.

Subject: [PATCH 2/3] fix(cloud-agent): keep unrebasable worktree review
 comments and editors

Do not drop a saved comment when its diff is missing and do not clear editor
text when it cannot be rebased. Show the retained editors in the review
dialog and add regression coverage for missing diffs, moved quotes and
unrebasable editors.

Subject: [PATCH 3/3] fix(cloud-agent): flag review comments kept on older
 captures

The review dialog now shows each comment's capture freshness and offers a
discard action for comments that are not on the current saved capture, so a
retained comment can be identified and removed before sending.
