 * @file schema.ts — Plugin tool schema normalizer.
 *
 * Converts a plugin-provided tool schema into a Zod raw shape accepted by
 * `McpServer.tool()`. Supports the three shapes plugin authors may provide:
 *   1. Zod raw shape        — { field: z.string() }            (preferred)
 *   2. Zod object schema    — z.object({ field: z.string() })
 *   3. Plain JSON Schema    — { type: "object", properties: { field: { type: "string" } } }
