Description
Consider adding support for:
- mmap
- msync
- munmap
To support mmap, we'll need a data structure to track memory regions that have been assigned to serve unifycr files so that we can distinguish our memory regions from normal system memory regions in calls to munmap and msync.

Research direction
Start by tracing the existing memory-mapping wrapper entry points and how UnifyFS file regions are represented. Review the mmap, msync, and munmap requirements, including how assigned regions must be distinguished from normal system memory. Done means all three wrappers are supported and region tracking prevents incorrect handling of unrelated mappings.
