4.0.0

⚠️ Breaking change

• Namespace renamed Soap\ → Meabed\ParallelSoap\. PHP 8.4+ reserves the top-level
  Soap\ namespace for the SOAP extension (Soap\Url, Soap\Sdl), so the client moved out of
  it. Update your imports:

  -use Soap\ParallelSoapClient;
  +use Meabed\ParallelSoap\ParallelSoapClient;

  The class name, public API and behaviour are unchanged. See UPGRADING.md.

🐛 Fixes

• PHP 8.4 / 8.5 fatal at autoload — __doRequest() now matches the parent's 6-argument
  signature; removed the deprecated curl_close(). (#179, thanks @c266 for #180)
• 100% CPU in parallel mode — doRequests() blocks on curl_multi_select() instead of
  busy-waiting. (#47)
• Proxy options were ignored — native proxy_host/proxy_port/proxy_login/proxy_password
  are mapped onto curl. (#11)
• The client can now be constructed with no options.

✨ Tooling & tests

• Hermetic local SOAP server test suite over HTTP and TLS (no network required).
• CI matrix across PHP 8.1–8.5 (+ lowest-deps + weekly cron); updated dev dependencies
  (PHPUnit 13, PHPStan 2, PHP_CodeSniffer 4).
• New docs: README, CHANGELOG.md, UPGRADING.md, and docs/development.md (architecture +
  diagrams).

Requirements: PHP 8.0+, ext-soap, ext-curl, ext-libxml.
