[Android Auto] Typing in search bar saves every character as an entry in YouTube search history

Duplicate Check

• I confirm I searched for existing reports and found no duplicates.

Describe the Bug

When using SimpMusic via Android Auto, typing in the search bar sends every single character typed as an individual query to YouTube's search history. This results in the search history being polluted with incomplete, character-by-character entries (e.g., c, cc, ccc, cccc, etc.).

Note: This behavior does not occur when searching directly from the smartphone application interface.

Steps to Reproduce

1. Connect the phone to Android Auto.
2. Open SimpMusic on the head unit display.
3. Open the search bar and type a query character by character (e.g., typing cccccc).
4. Check your YouTube search history (via YouTube app or web).
5. Notice that every intermediate typing step has been saved as an individual search history item.

Expected Behavior

Partial queries sent while typing on Android Auto should not pollute the YouTube search history. Only finalized searches (or proper debounced search submissions) should be added to the history, consistent with the smartphone app's behavior.

Log / Error Details

N/A (No crash occurred)

No files or tests are named. Start by tracing the Android Auto search handling and compare it with the smartphone application's search flow, then reproduce the character-by-character query behavior. Done means intermediate queries no longer create history entries and only finalized or properly debounced searches are recorded.
