chore: update dependencies and refactor GitHub integration

- Downgraded @types/node from ^25.0.0 to ^24.10.3 in package.json and package-lock.json.
- Replaced GithubIntegration with Octokit for GitHub API interactions in github.ts.
- Refactored GitHub API calls to use Octokit methods for listing repositories, pull requests, and issues.
- Added mapping functions for GitHub repository and pull request data.
- Removed pg-sql-tool.ts as it is no longer needed.
