Function expand_domain_inputs

pub fn expand_domain_inputs(
    domains: &[String],
    tlds: &Option<Vec<String>>,
) -> Vec<String>

Expand domain inputs based on smart detection rules.

Implements the smart expansion logic:

• Domains with dots are treated as FQDNs (no expansion)
• Domains without dots get expanded with provided TLDs
• Validates and filters out invalid domains

Arguments

• domains - Input domain names
• tlds - TLDs to use for expansion (defaults to [“com”] if None)

Returns

Vector of fully qualified domain names ready for checking.
