Module hosts 

Host-to-npub static mapping.

Provides a HostMap that resolves human-readable hostnames to Nostr public keys (npubs). Populated from two sources:

1. Peer alias fields in the YAML configuration
2. An operator-maintained hosts file (/etc/fips/hosts)

The DNS resolver checks the host map before falling back to direct npub resolution, enabling gateway.fips instead of npub1...xyz.fips.

Constants
