הורדת opencode 1.0.0

OpenCode 1.0 is a complete rewrite of the TUI.
We moved from the go+bubbletea based TUI which had performance and capability issues to an in-house framework (OpenTUI) written in zig+solidjs.
The new TUI works like the old one since it connects to the same opencode server.

Upgrading
You will not be autoupgraded to 1.0 if you are currently using a previous
version.
To upgrade manually, run
$ opencode upgrade 1.0.0

UX changes
The session history is more compressed, only showing full details of the edit and bash tool.
We added a command bar which almost everything flows through. Press ctrl+p to bring it up in any context and see everything you can do.
Added a session sidebar (can be toggled) with useful information.
We removed some functionality that we weren't sure anyone actually used. If something important is missing please open an issue and we'll add it back quickly.
