Vim-Style Command Line
Added a Vim-like command line to the TUI. Press : from normal-mode panes to run common actions such as :w, :q, :q!, :wq, :x, :e, :help, and :noh.
Search UX
Search behavior now more closely follows Vim: opening / starts with an empty prompt while keeping the previous search available for match navigation, and clearing the live search input clears current highlights.
The search prompt UI was also simplified by removing the extra search icon. This release also includes theming support.
