Address Gemini Feedback

First: Get PR info using the agentTool wrapper:

./scripts/agents/tooling/agentTool.ts getPrInfo --fields number,headRefName,url

Extract number as PR_NUMBER and url as PR_URL for use in subsequent commands.

CRITICAL: Never Create Pending/Draft Reviews

When replying to Gemini comments, you MUST use the REST API to create immediate comment replies. Do NOT use gh pr review or GraphQL review mutations - these create pending/draft reviews that remain invisible until submitted, and Gemini will never see them.

Always tag @gemini-code-assist in every reply to ensure Gemini receives a notification and responds.

See $follow-up-with-gemini for the correct API usage and examples.
