/**
 * Berget AI Auth Plugin for OpenCode — dual V1/V2 entrypoint
 *
 * The default export is the officially recommended dual shape
 * (see https://opencode.ai/v2/docs/build/plugins/migrate-v1):
 *
 * - **V2 CLIs** read `id` and `setup()`, ignoring `server()`. `setup()` is
 *   lazy: the V2 implementation (and its `@opencode/plugin` /
 *   `@opencode/schema` type imports) only loads when a V2 CLI calls it, so no
 *   V2 SDK code ever executes under V1.
 * - **V1 CLIs (>= 1.3.4)** detect the object form and call `server(input)`
 *   with the same `PluginInput` the previous default export received. The V1
 *   implementation is unchanged.
 *
 * `define` mirrors `Plugin.define`, which is the identity function; the local
 * alias keeps any runtime import of the V2 SDK out of the module V1 loads.
 * All `src/v2/` imports of the SDK are type-only (enforced by a unit test).
 *
 * V1 CLIs older than 1.3.4 cannot load object-form default exports — users on
 * those versions must pin `@bergetai/opencode-auth@1.1.1` (the last release
 * without the dual export; `@1` now resolves to the 1.2.x line).
 *
 * @example
 * ```json
 * // opencode.json (V1 CLI)
 * { "plugin": ["@bergetai/opencode-auth@latest"] }
 * // opencode.json (V2 CLI)
 * { "plugins": ["@bergetai/opencode-auth@latest"] }
 * ```
 *
 * @see https://berget.ai
 * @see https://opencode.ai/v2/docs/build/plugins
