opencode native 0.11.6

Added

• Go back to a prompt, from its right click. The files it would restore are shown, written back already as the server does it: Go back
  keeps it so and drops what came after, the prompt returning to the composer; Cancel, Escape or a click outside put the files back. If
  the program dies in between, the session brings the dialog back when opened. In a folder without snapshots it says only the
  conversation goes back.
• What a session changed, from its first prompt to its last, and what one prompt changed, each file with its diff.
• Move a session to another folder, from its right click or the palette.
• Export a session to a file and import it, on this machine or another; an export without the text, to share the shape of a session.
  A session already here is opened rather than refused.

Fixed

• A diff from git no longer shows its diff --git and index lines.

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).
