What's changed
Relax the twilio/sdk constraint from ^7 to ^7 || ^8, so consumers running on PHP 8.5 can adopt Twilio v8 (which fixes the implicit-nullable and curl_close() E_DEPRECATED notices that Twilio v7 emits under PHP 8.5).
No source changes — verified compatible with twilio/sdk 8.11.6: the Rest\Client/Rest\Api subclasses, the baseUrl request-routing override (Domain::absoluteUrl), the TwiML VoiceResponse/MessagingResponse subclasses, and Exceptions\TwimlException all remain intact.
This is a backward-compatible change: ^7 consumers are unaffected.
