Subject: [PATCH] fix: expose unload() JSI binding for TextToImageModule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TextToImage.unload() exists in C++ but was never registered as a JSI
host function, causing `TypeError: this.nativeModule.unload is not a
function` when calling BaseModule.delete() from JS.

Every other composite model (OCR, VerticalOCR, Kokoro, LLM) already
registers unload in its `if constexpr` block — this adds the same
one-liner for TextToImage.
