gemini-cli[bot] 868913e446 ## Metrics Standardization & Quality Fixes
This PR updates the metrics scripts to resolve lint errors and improve architectural consistency after the conversion to CSV format.

### 🛠 Fixes

1. **Lint Errors**: Resolved 6 `@typescript-eslint/no-unused-vars` errors by removing the unused `MetricOutput` import across the metric suite.
2. **License Standardization**: Removed redundant `@license` tags from all 8 metric scripts to match repository standards.
3. **GraphQL Consistency**: Updated `open_issues.ts` and `open_prs.ts` to use GraphQL variables (`-F`) and the `gh api graphql` pattern used by other scripts, improving security and readability.
4. **Output Consistency**: Migrated `open_issues.ts` and `open_prs.ts` from `console.log` to `process.stdout.write` for unified output behavior.
5. **Robust Execution**: Added `stdio: ['ignore', 'pipe', 'ignore']` to all `execSync` calls to ensure clean output streams and prevent unintentional inheritance of the parent process's stdio.
6. **Code Cleanup**: Removed the now-unused `MetricOutput` interface from `types.ts` and simplified `metrics/index.ts` by removing legacy JSON parsing logic.

### 🧪 Verification
- `npm run lint` now passes for all files in `tools/gemini-cli-bot/metrics/`.
- Validated all 8 scripts manually to ensure they still produce the correct CSV output.
