🤖 Gemini Bot: Productivity Optimizations & Workflow Verification

This PR implements several bot-related improvements and verifies workflow permissions as requested by maintainers.

### Changes:
1. **Fix Metric Cap (BT-01):** Refactored `open_issues.ts` and `open_prs.ts` to use GitHub's GraphQL API. This bypasses the 1000-item limit of the standard list command, ensuring accurate metrics for repositories with large numbers of open items.
2. **Initialize Pulse Reflexes (BT-02):** Created the `tools/gemini-cli-bot/reflexes/scripts` directory and added a README. This prepares the infrastructure for high-frequency reflexive automation.
3. **Workflow Verification (BT-05):** This PR and the accompanying comment on #24353 serve as confirmation that the GitHub App integration and workflow "write" permissions are correctly configured.

### Impact:
- Accurate tracking of repository backlog.
- Foundation for faster automated triage.
- Confirmed operational status of the bot.

+# Pulse Reflex Scripts
+
+This directory contains lightweight, high-frequency automation scripts executed by the Pulse workflow (`.github/workflows/gemini-cli-bot-pulse.yml`) every 30 minutes.
+
+## Purpose
+
+Pulse scripts are intended for "reflexive" actions that require faster response times than the daily Brain runs, such as:
+- Initial issue triage and labeling.
+- Detecting and responding to urgent triggers.
+- Basic maintenance tasks.
+
+## Script Format
+
+Scripts should be standalone TypeScript (`.ts`) files and will be executed using `npx tsx`.
