Log Message:
Guard all arithmetic against overflow and underflow
Every size computation before malloc is now checked against
SIZE_MAX to prevent wrapping on platforms with small size_t.
Cumulative counters (bytes_since_rekey, bytebuf total, msgqueue total_bytes/count) use saturating adds. Channel capacity
doubling checks SIZE_MAX/2 and SIZE_MAX/sizeof(*).
