The interactive multiselect loop nested key dispatch up to six indent
levels deep — the worst offender being the space-bar toggle
(while > if focus > elif key > if filtered > if/else membership) and
the long order-mode elif chain inside the focus branch.
Extract two behaviour-identical helpers:
- `_toggle_membership(items, item)` collapses the add/remove if/else,
pulling the space branch back to four levels.
- `_handle_order_key(key, selected, order_cursor)` moves the entire
order-focus dispatch out of the loop, returning the new cursor.
No control-flow or key-binding changes; the loop's early returns and
focus toggling are untouched. (git_gate.py's deep-looking lines named
in the issue are multiline call-argument continuations already under
four levels of control nesting, so no change was warranted there.)
Closes#288
