Add log dumping on program exit

- Add dumpLogsToConsole() function to output all logs when exiting
- Register exit handlers for graceful shutdown, SIGINT, and SIGTERM
- Dump logs to stderr to avoid interfering with normal program output
- Handle both error logs and console logs with clear section headers
