Description (problem / solution / changelog)

🤖 Implement Gemini PR Pre-review Reflex

This PR adds a new reflex action to the Gemini CLI Bot that automatically provides high-level pre-reviews for new pull requests.

Changes:

• Created tools/gemini-cli-bot/reflexes/scripts/pr_pre_review.ts: A reflex script that uses Gemini to evaluate PRs based on quality, roadmap alignment, "obvious wins," and repository best practices.
• Updated .github/workflows/gemini-cli-bot-pulse.yml: Added GEMINI_API_KEY and ensure the Gemini CLI is bundled before running reflex actions.

Impact:

• Time to First Response: Will decrease as the bot provides initial feedback within 30 minutes of PR submission.
• Maintainer Productivity: High-level assessments and roadmap alignment checks will help maintainers prioritize reviews.
• Contributor Experience: Immediate feedback on best practices and roadmap alignment.

This addresses the request in issue #26471.
