opencode native 0.5.1

Fixed

• A long conversation no longer slows every frame: only the messages near the view are built, the others stand as a
  space of their measured height (all are built again when the column's width changes, and while finding). Sweeping the
  pointer over the sessions of a long conversation drew about 21 frames a second; 60 now, measured.
• The dialogs' close cross sits clear of the scroll bar along a scrolling dialog's right edge.

Windows 10 and 11 (x64): one executable; run it, or install it for your user from its Setup (title bar menu > Setup...).
Linux (x64): the archive holds one program; run it, or ./opencode-native --install (an entry in the applications menu). Needs Vulkan, libxkbcommon, fontconfig, Wayland or X11.

It finds the opencode server of the computer by itself (another one: --url, or the status bar's server menu).
