Function keybind_scope 

pub fn keybind_scope(key: &str) -> &'static str

What: Determine the conflict-detection scope for a keybind action.

Inputs:

• key: Canonical keybind action key.

Output:

• Static label identifying the scope (global, search, search_normal, recent, install, or news).

Details:

• Two bindings collide only when they share both a chord and this scope.
• Same-chord rebinds across scopes (e.g. Left for pane_left and search_focus_left) are considered intentional and do not conflict.
