Pull Request Overview
This PR introduces a new GitHub Actions workflow to optimize the ephemeral GitHub Copilot coding agent environment by preinstalling dependencies and warming caches for faster iterative tasks.
Key changes:
- Creates a dedicated setup workflow that handles Node.js dependencies, build tools, and built-in extensions caching
- Implements retry logic for npm installation and uses cache restoration for faster subsequent runs
- Includes environment optimization by skipping unnecessary downloads (Electron, Playwright browsers)

The setup steps are generally too slow for a coding agent session. Currently without setup steps each sessions runs for 10 to 15 minutes, but with this complete setup steps it took ~8 minutes. |
