PLATFORM_MAX_PATH_LENGTH

#define PLATFORM_MAX_PATH_LENGTH   4096

Maximum path length supported by the operating system

Platform-specific values:

• Windows: 32767 characters (extended-length path with \?\ prefix)
• Linux: 4096 bytes (PATH_MAX from limits.h)
• macOS: 1024 bytes (PATH_MAX from sys/syslimits.h)

Note: Windows legacy MAX_PATH (260) is too restrictive for modern use. We use the extended-length limit instead.
