Pull request overview

This PR completes the breaking-change removal of the legacy “remember extension presence” mechanism by deleting the CanRememberExtensionPresence protocol and removing the related WebDriver helper methods, while updating Android’s Common extension to no longer depend on that protocol.

Changes:

• Removed assert_extension_exists / mark_extension_absence from appium.webdriver.webdriver.WebDriver.
• Deleted the CanRememberExtensionPresence protocol.
• Updated Android Common extension to drop CanRememberExtensionPresence from its base classes.

appium/webdriver/webdriver.py:440

• After removing the extension-presence helpers, the driver still initializes self._absent_extensions (and imports Set) but this attribute is now unused in the codebase. Keeping this dead state can confuse future maintenance and makes the feature removal incomplete; please remove _absent_extensions initialization and any now-unused typing imports.

    def _add_commands(self) -> None:
        # call the overridden command binders from all mixin classes except for
        # appium.webdriver.webdriver.WebDriver and its sub-classes
