This change introduces a new `scrollback` Meson build option (enabled by default) that lets foot be compiled without scrollback history. When the option is off, `FOOT_HAVE_SCROLLBACK` is left undefined and the relevant code is excluded from the build, producing a slimmer terminal for use cases that do not need it. With scrollback disabled: - The `[scrollback]` section in `foot.ini` and its key bindings become no-ops. - In-terminal search is removed, along with the "pipe scrollback" action, the scrollback indicator, and their colors/overlays. - IME hooks for the search box, mouse-wheel scrollback handling, and related `terminal` state are compiled out. - Selection auto-scroll (the timer that scrolls the viewport while a drag-selection extends past the visible area) is removed, since with no scrollback there is nowhere to scroll to. The associated function declarations, `enum selection_scroll_direction`, the `auto_scroll` field on `terminal::selection`, and their init/teardown sites are all excluded from the build. To keep action enumerations stable across build configurations, two range markers (`BIND_ACTION_PIPE_FIRST` / `BIND_ACTION_PIPE_LAST`) are introduced so that pipe-action handling does not depend on `PIPE_SCROLLBACK` being present. The build summary and `foot --version` now report `+scrollback` or `-scrollback`, and the config tests have been updated to account for optional section.
