Find new exceptions thrown without the caught exception

Recipe IDorg.openrewrite.staticanalysis.FindNewExceptionWithoutCause

Artifactorg.openrewrite.recipe:rewrite-static-analysis

Finds catch blocks that throw a newly created exception without referencing the caught exception, which discards the original exception's stack trace and message. Data flow (taint) tracking is used to establish whether the caught exception—or any value derived from it—reaches the thrown exception, so indirect references through local variables and string concatenation are not falsely reported. This mirrors PMD's PreserveStackTrace rule.
