Find `LIKE` patterns starting with a wildcard

Recipe IDorg.openrewrite.sql.antipattern.FindLeadingWildcardLike

Artifactorg.openrewrite.recipe:rewrite-sql

A LIKE pattern whose first character is % or _ gives the database no prefix to seek in a B-tree index, so every row must be inspected. When a prefix search is not possible, a trigram or full-text index can serve the query instead. Parameter placeholders and patterns with only trailing wildcards are not flagged.
