OpenCode 2.2 adds desktop plugins, with a breaking SDK change

What changed

Users can now create, install and share desktop plugins (experimental), and the desktop app has a new look. Plugins can attach named instructions to a session without rewriting the system prompt, which keeps the prompt cache intact, and prompt-cache lifetimes can be set per provider and model. Breaking change: the root of the @opencode/ai package now exports the Promise API, with the Effect API moved to @opencode/ai/effect.

Who it affects

OpenCode desktop users, and SDK and plugin authors.

What to do

Update @opencode/ai imports before upgrading.
