swoole 6.1.2

- No longer throw warnings when failing to set the `socket` receive/send buffer size
- Fixed an issue in `Swoole\Http\Server` where the `onClose` callback might execute before `onRequest` when handling `HTTP2` requests, leading to a use-after-free problem
- Optimized the `getSocket()` method by duplicating the file descriptor when exporting the `php sockets` resource object, preventing `php sockets` from affecting the `socket` held by `Swoole` upon closure
- Fixed a memory leak issue in `Swoole\Async\Client`
- Fixed an issue where `Swoole\Coroutine\Http\Client` of `IPv6` type could not use `Socks5` proxy
- Synchronized updates to adapt to relevant changes in the `CURL` extension in `PHP 8.4`
- Added the `async.file://` file protocol, which allows enabling coroutine scheduling for specific file operations even when global file coroutine support is disabled
