Log Message:
Enable -Wconversion: range-checked narrowing throughout

All implicit narrowing conversions replaced with range-checked
intermediate variables.  Library code checks both lower and upper
bounds before every narrowing assignment, with overflow guards
before arithmetic.  Test code uses explicit casts where safe.

Hardening audit now 34 of 34 OpenSSF flags.
