Description

### Describe the problem you're observing

All the current examples include `unifycr.h` and require linking against either `libunifycr` or `libunifycr_gotcha`. This means there is no way to build a baseline version that does not use UnifyCR. The baseline version is necessary for verifying base functionality of the example and for performance comparisons against the UnifyCR-enabled versions.

For example, see PR #177 where I have modified the `sysio_writeread.c` example to have a pure POSIX target build. The other examples need something similar.

Research direction

Read PR #177 and its changes to sysio_writeread.c first, then inspect the other examples and their build targets for the same UnifyCR-only dependency. Confirm that each example has a pure POSIX baseline target as well as its UnifyCR-enabled build, and verify both versions can be built for comparison.
