fix: Skip PDF integration tests in CI

PDF generation tests require a running HTTP server for chromedp to connect to.
This is not available in CI environment, causing tests to fail with ERR_CONNECTION_REFUSED.

Changes:
- Added skip condition to TestDefaultCVShortcut when running in short mode
- Updated CI workflow to use -short flag for tests and benchmarks
- Removed Chrome installation from CI (not needed for unit tests)
- Integration tests can still run locally without -short flag
