chore: mark @hono/bun-compress as deprecated (#1809)

* chore: mark @hono/bun-compress as deprecated

Bun now supports CompressionStream natively, making this middleware
unnecessary. The README already stated it would be deprecated once
Bun added support.

- Add deprecated field to package.json
- Update README with deprecation notice and migration guide
- Point users to the built-in hono/compress middleware

Closes #1807

* Add patch changeset for bun-compress deprecation

 # Bun Compress Middleware for Hono
 
-Bun does not currently support the [CompressionStream API](https://developer.mozilla.org/en-US/docs/Web/API/CompressionStream) so this middleware replicates the behavior of [`hono/compress`](https://hono.dev/docs/middleware/builtin/compress) using the Zlib library. This middleware will be deprecated once [Bun adds support for `CompressionStream`](https://github.com/oven-sh/bun/issues/1723).
+> **Deprecated**: Bun now supports the [CompressionStream API](https://developer.mozilla.org/en-US/docs/Web/API/CompressionStream) natively (since [oven-sh/bun#1723](https://github.com/oven-sh/bun/issues/1723) was resolved). Use the built-in [`hono/compress`](https://hono.dev/docs/middleware/builtin/compress) middleware instead.
 
-This middleware will use `hono/compress` if CompressionStream is available so you can use this middleware in Bun and Node.js without any changes.
+This middleware was created as a workaround for Bun's missing `CompressionStream` support. Now that Bun has added native support, `hono/compress` works on Bun without any polyfill.
 
-## Import
+## Migration
+
+Replace:
 
 ```ts
-import { Hono } from 'hono'
 import { compress } from '@hono/bun-compress'
 ```
 
-## Usage
+With:
 
 ```ts
-const app = new Hono()
-
-app.use(compress())
+import { compress } from 'hono/compress'
 ```
 
-## Options
-
-### <Badge type="info" text="optional" /> encoding: `'gzip'` | `'deflate'`
-
-The compression scheme to allow for response compression. Either `gzip` or `deflate`. If not defined, both are allowed and will be used based on the `Accept-Encoding` header. `gzip` is prioritized if this option is not provided and the client provides both in the `Accept-Encoding` header.
-
-### <Badge type="info" text="optional" /> threshold: `number`
-
-The minimum size in bytes to compress. Defaults to 1024 bytes.
+No other changes needed — the API is the same.
