Detailed Description

Error codes and status values for ascii-chat.

Single enum for both function return values and process exit codes. Following Unix conventions: 0 = success, 1 = general error, 2 = usage error.

Error codes are organized into ranges:

• 0: Success
• 1-2: Standard errors (general, usage)
• 3-19: Initialization failures
• 20-39: Hardware/Device errors
• 40-59: Network errors
• 60-79: Security/Crypto errors
• 80-99: Runtime errors
• 100-127: Signal/Crash handlers
• 128-255: Reserved (128+N = terminated by signal N on Unix)
