// opencode TUI plugin: one key toggles the whole "verbose view".
//
// The session view keeps four independent display toggles in the TUI's persisted KV store
// (~/.local/state/opencode/kv.json). Built-in commands only flip one each. This plugin reads all
// four and drives them to the same state: if every one is on, turn all off; otherwise turn all on.
// Writing the KV keys directly is what the built-in toggles do too (kv.signal is a reactive
// store), so the open session re-renders immediately and the choice survives restarts.
//
// Declared in tui.json:  "plugin": [["./tui-plugins/verbose.ts", { "key": "<leader>v" }]]
// (TUI plugins are never auto-discovered, and this dir is deliberately NOT ~/.config/opencode/plugins/,
//  which the server-side plugin loader scans and would reject a TUI-only module.)
// Also available as /verbose and from the command palette.
