build(deps): Update jacobsa/fuse to support co-existence of vectored and non-vectored reads

[vipnydav]

Description

This PR updates the github.com/jacobsa/fuse dependency to commit d2942a9.

This update allows for both vectored and non-vectored reads to coexist, which provides more flexibility in how read operations are handled. Previously, the UseVectoredRead mount option determined the read buffer strategy. With this change, the FUSE library will always provide a destination buffer (ReadFileOp.Dst). File systems can then optionally provide their own data buffers (ReadFileOp.Data) to take advantage of vectored reads and avoid extra memory copies.

This simplifies the read implementation and removes the need for the now-legacy UseVectoredRead flag.
