Plugin silently fails to load when it exports a non-function value #31575

Description

A plugin that exports anything besides the plugin function — a constant, an array — silently fails to load. No error, the hooks just never fire.

It's getLegacyPlugins in packages/opencode/src/plugin/index.ts: it loops over every export and throws on the first non-function one, and that error gets swallowed by the Effect.catch right below it (the one with the // TODO: make proper events for this comment).

Using the export default { id, server } format works around it, since that path skips getLegacyPlugins entirely — but the docs only show the named-export style, so it's easy to hit. A continue instead of the throw would fix it.

Steps to reproduce

1. Create a plugin that exports a constant next to the function:

export const VERSION = "1.0.0";
export const MyPlugin = async () => ({
  "tool.execute.before": async () => { console.log("hook fired"); },
});

2. Add it to opencode.json: "plugin": ["file:///path/to/plugin.js"]
3. Trigger any tool — the hook never fires, and there's no error anywhere.
