Require BOOTP chaddr match for host→VM DHCP responses (#192) 
* Require BOOTP chaddr match for host→VM DHCP responses

Mirror #191 request-path identity checks: admit/forward DHCP
BootReplies only when chaddr matches the VM MAC, so foreign
client replies are not written into the guest fd.

Exit Softnet when its VM socket disconnects (#193) 
Check the VM socket on poll timeouts because macOS kqueue does not
report Unix datagram peer disconnects. This prevents orphaned
Softnet processes from blocking VM cleanup.
