Add ---@return nil before M.clear_query. Keep the exported function typed as fun(): nil.

Focus the input window in M.clear_query(). This exported function only moves the cursor in S.input_win. If the list or preview has focus, typing does not enter the prompt. Reuse P.focus_input_win() or document an input-only contract.

Register clear_query after insert_newline_escape.

When both options use the same insert-mode key, the later expression mapping replaces P.clear_query. Outside grep mode, it returns '', so clearing does nothing. This affects both prompt positions.

clear_query mapping wins when both options share a key.
