Log Message:
Wrap all non-C17 calls behind platform abstraction layer

Create plat_stricmp (wraps strcasecmp/stricmp), plat_fsopen (wraps
_fsopen), plat_CreateSemfile (NFS-safe on Unix, fopen "w+x" elsewhere), plat_mkdir, plat_GetExePath, plat_getmode, and plat_chmod. Move
DirExists from platform.c into the per-platform wrapper files.

Replace all 116 strcasecmp call sites with plat_stricmp. Replace all _fsopen/_SH_DENY* call sites with plat_fsopen/PLAT_SH_DENY*. Replace
MKDIR macro, GetModuleFileName/fullpath exe-path logic, stat()-based
permission capture (chew.c), and chmod()-based permission restore
(install.c) with platform wrappers.

On Windows, add a real strdup() function (conditional on C < C23) to
replace the old #define macro. Remove stale #includes from myibbs.c.

Eliminate all #ifndef __unix__ and #ifdef __unix__...#else patterns;
replace with explicit platform guards so new ports don't silently get
wrong behavior. Simplify FAR macro to default empty unless __MSDOS__.

Update docs/functions.md with ~60 previously undocumented functions
(fight.c second half, empire.c first half, user.c first half, new
platform wrappers). Update docs/testability.md with new sections,
corrected D/T markings, and clarified Non-C17 column rules.

Refactor test_semfile.c to use mock-driven plat_CreateSemfile instead
of real filesystem operations. Add mocks_platform.h shared test stubs.
