ad7698d530 feat: add icmp_set_dont_fragment and next_mtu extraction 
- Add icmp_set_dont_fragment() using IP_MTU_DISCOVER/IP_PMTUDISC_DO
- Add next_mtu field to icmp_offending_packet_t, populated from the
  outer ICMP header on type=3/code=4 (frag needed) replies
- Fix extract_offending: read MTU from outer ICMP, not embedded packet
- Update test to match corrected extraction semantics
- Clean up checksum odd-byte handling with a static zero sentinel
