- Extract shared DeferClose helper, removing 14 duplicate copies - Rename PlayWright-prefixed types to cleaner names (BrowserOptions, BrowserSelection, NewBrowser, etc.) - Rename fields: ServerAddress, RequireServer (was DontLaunchOnConnectFailure) - Extract shared initBrowser/mergeOptions into browser_init.go, deduplicating ~120 lines between NewBrowser and NewInteractiveBrowser - Remove unused locator field from document struct - Add tests for all previously untested packages (archive, aislegopher, wegmans, useragents, powerball) and expand existing test suites - Add MIGRATION.md documenting all breaking API changes Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
