Quick bug-fix release bringing improvements to our Fruity backend, and basic support for iOS 18.4:

• darwin: Update injector dyld init detection for iOS 18.4.

• fruity: Update injector dyld init detection for iOS 18.4 (#1154). Thanks to @pachoo for this contribution.

• network-stack: Reduce delay between writes. By flagging as writable as soon as some space is available, without waiting for the low watermark. Thanks to @mrmacete for this improvement.

• network-stack: Fix TCP write chunk length (#1156). Another fix by @mrmacete.

• network-stack: Always send enqueued data. This change ensures pcb.output() is called even when no more space is available on the queue, preventing stalls. Credits to @mrmacete for preventing those pesky stalls.
