Description

• Hides favorites when toggling to search on a Duck.ai tab

Steps to test this PR

With native input enabled

• Add a favorite
• Go to Duck.ai
• Toggle to search
• Verify that the favorite does not show
• Type something
• Clear it
• Verify that the favorite does not show

---

Note

Low Risk
Low risk: small, localized callback changes in NativeInputManager affecting autocomplete clearing behavior, with minimal impact outside Duck.ai mode.

Overview
Adjusts native input callback handling so that in Duck.ai mode clearing the search field triggers onClearAutocomplete (instead of propagating an empty onSearchTextChanged).

Also updates search-tab selection handling to clear autocomplete and short-circuit further selection behavior when the text is blank in Duck.ai mode.
