feat: add deferred response buffering, TableDataProvider, and stealth improvements

- ApiResponse: add readToBuffer option to defer/stream body instead of eagerly buffering
- TableDataProvider: implement HTML table parser with per-column provider support
- StealthConfig: add 10s page load timeout and copyCookiesFrom parameter for cookie sharing
- StealthUnitDownloader: catch WebDriverTimeoutException on navigation, log warning instead of throwing
- Bump version to 2.9.0
