- Avoided value-imports of `puppeteer-core` in main startup files to prevent eager loading of the browser-data dependency graph. - Used `import type` and literal string checks to defer `puppeteer-core` initialization until browser tools are actually invoked. - Added a test to verify that `puppeteer-core` and `@puppeteer/browsers` remain off the eager startup import graph. - Externalized additional heavy dependencies to reduce bundle size and improved minification settings in the build script.
