opencode desktop(windows) load superpowers failed because of fails to load plugins: tries to install @opencode-ai/plugin@local, which is not a published npm version

Description

superpowers is a famous skill series: https://github.com/obra/superpowers.
Even after registry it as a plugin in opencode.json:
"plugin": ["~/.config/opencode/node_modules/superpowers"]
opencode desktop still can not find these skill.
Here is the reason:

1. @opencode-ai/plugin is a valid npm package (npm view @opencode-ai/plugin version dist-tags returns latest: 1.18.4), but it has no version or dist-tag called local. So a request for @opencode-ai/plugin@local always fails.
2. OpenCode Desktop requests exactly that — @opencode-ai/plugin@local — as part of the plugin dependency install on every startup. Since local is not a real version, it looks like a placeholder that was never resolved to a real version number before being handed to the installer.
3. This failed @opencode-ai/plugin@local dependency is part of plugin dependency preparation, so plugins loaded through the Bun install path (npm package names / git specs in the plugin array) fail to install and never load.

Below are logs on every startup:

   {
   "plugin": ["superpowers@git+https://github.com/obra/superpowers.git"]
   }
2. Restart OpenCode.
3. The plugin does not load. The log shows a repeated @opencode-ai/plugin@local install failure on every startup.
