Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The new clear-query action can be overridden by another default insert-mode mapping, leaving users unable to clear the picker input in affected configurations.

- Around line 321-322: Add the LuaDoc annotation `---@return nil` immediately
before the exported function `M.clear_query`, preserving its typed signature as
`fun(): nil`.
- Around line 321-331: Update M.clear_query() to focus S.input_win via the
existing P.focus_input_win() helper before or alongside positioning the cursor,
so typing enters the prompt even when another picker window currently has focus.
In `@lua/fff/picker_ui/ui_creator.lua`:
- Line 344: Update the insert-mode mappings in the picker UI setup around
set_keymap and the clear_query/preview_scroll_up bindings so clear_query and
preview_scroll_up always use distinct keys, while preserving existing nil
behavior. Ensure the mapping logic works correctly for both prompt positions and
add coverage for the collision case where clear_query is <C-u>.
Apply the same fix in `@lua/fff/picker_ui/ui_creator.lua` at line 344.

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.

Prevent clear_query from being overwritten by preview_scroll_up. If users configure both actions to the same insert-mode key, the later mapping wins and the new action becomes unavailable. Register the mappings without collisions or reject duplicate keys.

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.
