Add configurable log level as optional CLI argument

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.
