Checks if a value is a valid IRI.
Validates IRIs according to RFC 3987 with variant-specific rules:
"hierarchical"
scheme:/...
"absolute"
scheme:...
"internal"
/...
"relative"
For non-absolute variants, rejects paths where .. segments would climb above the root.

The value to validate as an IRI
The identifier variant to validate against (default: "relative")
true if the value is a string conforming to IRI syntax rules for the specified variant; false otherwise
true
false
This function serves as a type guard, narrowing the type from string to IRI when used in conditional checks.
