Feature: Add ability to batch comments instead of submitting one by one

[areibman]

Feature Request

Add the ability to write multiple comments and submit them all at once, similar to GitHub's "Start a review" feature.

Problem

• Each comment triggers a separate notification
• Can't review all comments before sending
• Creates notification spam for reviewers
• No way to provide cohesive feedback across multiple files

Proposed Solution

Batch Comment Mode

1. Start Review: Click "Start review" button instead of immediate comment submission
2. Add Comments: Write multiple comments across different files/lines (marked as "pending")
3. Submit All: Submit all pending comments at once with optional summary

Key Features

• Visual indicators for pending comments
• Edit/delete pending comments before submission
• Preview all pending comments
• Submit with review status (comment/approve/request changes)
• Auto-save drafts locally
• Single notification for all comments

UI Elements

• Batch mode indicator with pending comment count
• "Pending" badge on unsent comments
• Submit review button with comment summary option
• Clear visual distinction between pending and submitted comments

Benefits

• One notification instead of many
• Better organized feedback
• Ability to review before sending
• Can cancel if needed

Acceptance Criteria

• Can enter/exit batch mode
• Add multiple comments without immediate submission
• Edit/delete pending comments
• View all pending comments
• Submit all at once
• Drafts persist through refresh
• Clear batch mode indicators
• Single notification sent

Similar To

• GitHub's "Start a review" for PRs
• GitLab's batch comments
• Bitbucket's draft comments
