Add LICENSE, AGENTS.md, and richer package.json metadata

Make the published npm package easier to discover and consume:

- LICENSE (MIT) so the published tarball ships with explicit terms.
- AGENTS.md is the dedicated agent-facing playbook covering install,
  the typed client surface, auth, error handling, and rate limits.
- package.json gains an English description, license=MIT, an
  uapis.cn homepage, an issues URL, and npm-search-friendly keywords
  (uapi, uapis.cn, sdk, typescript, public-api, openapi, ...).

No code changes; build/publish pipeline is unaffected.

+# AGENTS.md — uapi-sdk-typescript
+
+This file tells AI coding agents how to use the **official TypeScript /
+Node.js SDK** for the [uapis.cn](https://uapis.cn) public API platform.
+
+## What this package is
+
+Strongly-typed Node / browser-compatible client for UAPI. Generated from the
+live OpenAPI 3.1 spec at <https://uapis.cn/openapi.json> — so the method
+list, parameter shapes, and return types stay in lock-step with the real
+API.
+
+```bash
+npm i uapi-sdk-typescript
+# or
+pnpm add uapi-sdk-typescript
+# or
+yarn add uapi-sdk-typescript
+```
+
+## Quick start
+
+```ts
+import { UapiClient } from "uapi-sdk-typescript";
+
+// Free-tier endpoints don't need an API key
+const client = new UapiClient("https://uapis.cn");
+
+const weather = await client.misc.getMiscWeather({ city: "北京" });
+console.log(weather);
+
+// Paid endpoints take a key
+const paid = new UapiClient("https://uapis.cn", process.env.UAPI_KEY!);
+const ocr = await paid.image.postImageOcr({ url: "https://…/photo.png" });
+```
+
+The client is grouped by tag (`misc`, `network`, `text`, `image`, `social`,
+`translate`, `search`, …) and each method name matches the underlying
+`operationId` from the OpenAPI spec.
+
+## Discovery
+
+When generating code, agents should:
+
+1. Pull the spec from <https://uapis.cn/openapi.json> if the schema you need
+   isn't already in your local types.
+2. Map the operation's `operationId` to a SDK method (`get-misc-weather` →
+   `client.misc.getMiscWeather`).
+3. Pass the request parameters as a single object — query params, path
+   params, and body all live there.
+
+## Authentication
+
+- Many UAPI endpoints (network, text, random, convert, weather, time,
+  hotboard) work with no key.
+- Paid endpoints want `X-API-Key`. The SDK forwards the second
+  `UapiClient` constructor argument to that header.
+- For human-in-the-loop OAuth flows, see
+  <https://uapis.cn/.well-known/oauth-authorization-server>.
+
+## Errors
+
+Every method throws an `AxiosError`-shaped error on non-2xx responses. The
+error body is a JSON object: `{code, success: false, error, request_id?}`.
+Surface the `error` text verbatim.
+
+## Rate limits
+
+Headers `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`,
+`Retry-After` are returned on every response. Honor them — back off on
+`429` and obey `Retry-After`.
