Recognize case-insensitive comparisons of
URI.getHost()against constant string allowlist entries, including equality checks through local variables and casts. This reduces false positives injava/ssrfandjava/unvalidated-url-redirection.New matches require actual String comparison methods and preserve the connection between the checked host and the URI. Tests cover reassignment, different URIs, bypassed guards, and untrusted comparison values.
Partially addresses #22259. Stream and helper-based checks remain unresolved.
