allowing CIDRs, wildcards and Plural in IP and DNS

[entlein]

Overview

network-wildcards: DNS leading/trailing/mid + CIDR + IPAddresses + "*" sentinel

Additional Information

CEL networkneighborhood helpers now query
projected fields with wildcard/CIDR/DNS-wildcard support and the v0.0.2
spec semantics (port/protocol checks degrade to address-only in v1
when only a CIDR is declared).

• DNS leading-* (RFC 4592 single-label wildcard)
• DNS trailing-* (subdomain-prefix wildcard)
• DNS mid-⋯ (interior dynamic segment)
• IPv4/IPv6 literals and CIDR ranges
• * any-IP sentinel
• IPAddresses list (deprecated single-IP field) preserved on the
  decode path

How to Test

20 declarative fixture YAMLs under tests/resources/network-wildcards/
pin the wildcard contract end-to-end:

• Literal IPv4/IPv6
• CIDR IPv4/IPv6
• * any-IP and * as CIDR
• Mixed IP list
• Deprecated IPAddresses field path
• DNS literal, leading wildcard, mid-⋯, trailing-*
• Trailing-dot normalisation
• Recursive * rejection
• Egress-and-ingress, egress-none
• Realistic Stripe API scenario
• Cluster DNS via mid-⋯
• Port+protocol with CIDR
• Multi-container mixed wildcards
