# Fix: 1000-issue metric cap for accurate repository health tracking

## Description
This change updates the `open_issues` and `open_prs` metric scripts to use the GitHub Search API (`gh api search/issues`) instead of `gh issue list` and `gh pr list`.

## Why it is recommended
The current scripts use a hardcoded `--limit 1000`, which caused the `open_issues` metric to cap at 1000. This masks the true size of the repository backlog and prevents accurate analysis of maintenance burden and throughput.

## Expected Metric Improvement
- `open_issues` and `open_prs` will now reflect the true total counts, even if they exceed 1000.
- This will allow for more accurate delta calculations and historical trends.

## Impact
This is a low-risk change that significantly improves data quality for the Gemini CLI Bot Brain, enabling better-informed decisions regarding stale issue management and contributor latency.
