v0.1.2

• Fix a 32-bit fseek truncation on Windows: dit-bf16.gguf and t5-bf16.gguf are 2.4-2.6GB, past the 2GB boundary where MSVC's 32-bit long truncates fseek's offset. This surfaced as "t5 load failed" on Windows (any backend) while working fine on Linux. Now uses a proper 64-bit seek (_fseeki64/fseeko).
