feat(sdk): improve Python SDK ergonomics

- Position browser-cli as a CLI plus Python SDK in docs and package metadata.
- Add public target properties and a raw command escape hatch for unsupported commands.
- Add convenience helpers for opening, finding, closing, and accessing tabs.
- Add plural group aliases and a wait_for_selector DOM convenience alias.
- Extend bound Tab objects with screenshot, pin, refresh, load wait, and URL watch helpers.
- Preserve remote auth key configuration when binding remote Tab and Group objects.
- Bump project and extension versions to 0.9.9 and cover SDK additions with tests.
