feat(read): target any tab for page info and extraction

- Add --tab option to all extract commands and page info
- Thread tab_id through the SDK extract and page namespaces
- Route page.info with a tab_id to tabs.status for cross-tab metadata
- Accept tab_id in the MCP page_info, extract_text, extract_markdown tools
- Forward tabId in the extension page.info and extract.html handlers
- Keep the active tab as default when no tab is given

- Cover tab-scoped reads in API, CLI, and MCP tests
- Bump package and extension version to 0.16.7
- Refresh uv.lock with current dependency versions
