Updated the selector for removing selectize items to target only direct children, ensuring correct clearing behavior. Enhanced the test app to display selected values and expanded the test cases to verify selection and clearing of multiple choices.
Imported Inputs, Outputs, and Session from shiny.session and updated the server function signature to include type annotations for improved type safety and clarity.
Refactors the selection logic to only remove items not in the desired set and only add missing items, improving efficiency and correctness when updating selected values in InputSelectize.

The
InputSelectize.setmethod has been enhanced to provide more intelligent option selection. It now carefully examines the currently selected options and compares them with the user's desired selections. When an existing selected option is not part of the user's intended choices, the method automatically selects that option and removes it by pressing the Delete key, ensuring a clean and precise selection process that aligns with the user's expectations.Added regression test and example app to verify that selections are properly cleared when setting an empty list.
