Migrate lytics-playwright to use @lytics/playwright-core

[prosdev]

Branch: feat/migrate-to-playwright-core-packages

Priority: High

Estimate: 2-3 hours

Parent Epic: #1

Dependencies: #2, #3, #4

Description

Update lytics-playwright repository to consume packages from the @lytics/playwright-core monorepo instead of using internal reporter implementation. This completes the extraction and demonstrates that the new packages work as drop-in replacements with no loss of functionality.

Acceptance Criteria

• All existing tests pass with new packages (100% pass rate)
• No old reporter code remains in lytics-playwright repository
• CI/CD pipeline works with new dependencies
• Test execution performance is same or better (≤12 minutes)
• Firestore reporting continues to work correctly (all collections populated)
• Slack notifications continue to work correctly (messages sent on failure)
• Documentation updated to reference new packages

Technical Requirements

• Install @lytics/playwright-annotations, @lytics/playwright-reporter, @lytics/playwright-adapters-internal
• Update reporter.ts to import and use CoreReporter from package
• Update slack-reporter.ts to use SlackAdapter (if migrated)
• Remove src/reporter/ directory entirely
• Remove src/types/core.ts file
• Update all test imports (if any reference reporter internals)
• Run full regression suite to validate
• Update CI/CD to authenticate with GitHub Packages (for internal packages)
• Update README.md and internal docs

Notes

• This is a breaking change for lytics-playwright but isolated to that repo
• Should be done after all core packages are published and stable
• Consider doing thorough QA in staging environment before production
