feat: resolve Browse shortcuts through input.kdl's cce-files domain

open_file, enter_dir, parent_dir, select_next/select_prev,
delete_entry, and toggle_hidden are resolved once at startup from
input.kdl (cce-files domain → cce-ui domain), defaulting to the
historical vim-ish keys. Arrow keys, Backspace, and Escape stay fixed.
Shortcuts now require exact ctrl/shift state (ctrl+j no longer
triggers the bare-j handler).
