fix: add postinstall hook to install chrome

- Added a postinstall script to trigger the Puppeteer browser installation for Chrome.
- Ensures the required browser binary is available after package installation to prevent runtime failures.
- Bumped the package version to 0.0.5 to reflect the configuration changes and dependency fixes.
