*	Add configurable log level as optional CLI argument	Thomas Vanbesien	3 days	1	-23/+23
\| \| \| \| \| \| \| \| \|	All three programs now accept an optional second argument [log-level] (trace, debug, info, warning, error, fatal) defaulting to info. The level is applied by setting the logger context pointer directly, avoiding a memory leak that would occur from overwriting the heap-allocated logger struct. Also documents the ASan leak-check workflow in CLAUDE.md.
*	Replace CLI arguments with config-file parser and add integration tests	Thomas Vanbesien	3 days	19	-0/+412
	Introduce a reusable key=value config parser (config.h/c) and convert all three programs to read their settings from config files instead of positional command-line arguments. Add example config files in config/ and 6 CTest integration tests covering None/Basic256Sha256/Aes128 with anonymous and user authentication. Remove the now-obsolete launch.sh.
