 * Compose client-side {@link ToolAdapter}s into ONE merged tool manifest and ONE
 * routed `onToolCall`. This is the single injection point for "available tools"
 * into the iframe: every adapter — client-side (GraphQL/REST/custom, run by your own
 * `execute` callback) or server-relayed ({@link createYakServerAdapter}) — contributes
 * its tools to the merged manifest and its executor to the routed handler. Because every
 * tool now flows through `onToolCall`, they all surface through `onToolCallComplete` /
 * `useYakToolEvent`.
 *
 * @example
 * ```tsx
 * const toolset = createYakToolset([
 *   createYakServerAdapter({ endpoint: "/api/yak" }),               // tRPC + custom server tools
 *   createGraphQLToolAdapter({ name: "shop", schema, execute: runShopQuery }),
 *   createRESTToolAdapter({ name: "billing", spec, execute: callBillingApi }),
 * ]);
 *
 * <YakProvider
 *   getConfig={async () => ({ routes, ...(await toolset.getConfig()) })}
 *   onToolCall={toolset.onToolCall}
 * />;
 * ```
