- Add Windows implementation of default_CSPRNG() using CryptGenRandom
- Add fallback stub for platforms without CSPRNG support
- Fix build.sh to properly detect build failures (use PIPESTATUS)
- Show proper error message instead of "Build completed successfully" on failure
- Create test_utils.h with cross-platform utility functions:
* test_mkdtemp() - Windows uses GetTempPath + _mkdir, Linux uses mkdtemp
* test_unlink() - Windows _unlink, Linux unlink
* test_rmdir() - Windows _rmdir, Linux rmdir
- Update all test files to use test_utils.h
- Replace arpa/inet.h and netinet/in.h with platform_compat.h
- Replace unistd.h with conditional includes
- Replace mkdtemp(), unlink(), rmdir() with test_* versions
- Tests now build on both Linux and Windows
- Note: Some integration tests may fail on Linux due to test environment
- Fixed incorrect init_connections() call in test_etcp_simple_traffic.c (was calling server_instance instead of client_instance)
- Fixed double free in timeout_heap_pop() when handling deleted elements
- Enhanced NULL pointer safety in uasync_print_resources() by removing complex heap manipulation
- Added debug logging to timeout_heap_pop() for better error tracking
Test results: test_etcp_simple_traffic now passes without double free errors
