plugin_enabled tui.json option is undocumented

Description

plugin_enabled is the only tui.json option with no documentation anywhere.

It is in the schema (packages/tui/src/config/index.tsx:66):

plugin_enabled: Schema.optional(Schema.Record(Schema.String, Schema.Boolean)),

and read at runtime (packages/opencode/src/plugin/tui/runtime.ts:478):

function pluginEnabledState(state: RuntimeState, config: TuiConfig.Resolved) {
  return {
    ...readPluginEnabledMap(config.plugin_enabled),
    ...readPluginEnabledMap(state.api.kv.get(KV_KEY, {})),
  }
}

I checked all twelve tui.json keys against the docs — theme, keybinds, plugin, leader_timeout, attention, prompt, scroll_speed, scroll_acceleration, diff_style, cursor and mouse are all covered. Only plugin_enabled appears in no .mdx file, so this is an isolated gap rather than a general one.

One behaviour worth documenting alongside it, visible in the snippet above: the KV store is spread after the config, so a plugin toggled from the command palette overrides whatever tui.json says, permanently, until it is toggled back. Someone who sets "plugin_enabled": { "x": false } after having toggled x on in the UI will find the config apparently ignored. That precedence looks deliberate — the runtime toggle is the more recent user intent — but it is surprising enough to be worth a sentence in the docs.

(While checking this I noticed plugin and prompt are in the tui.json schema but not in the Options list in tui.mdx either, though plugin is covered in the plugins docs. I left those alone since I have not traced their behaviour.)
