Like predicate does not escape % and _ wildcards in the bound value

[jkalias]

Problem

Like::GetSqlValue (src/query_predicates.cc:97) builds the comparison value as %value% but does not escape % or _ characters contained in the value itself, and the generated LIKE clause (QueryPredicate::Evaluate) has no ESCAPE clause.

Impact

If the user-supplied value contains % or _, those characters act as LIKE wildcards rather than literals, so the match semantics differ from what the caller intended (e.g. searching for 50% matches far more than the literal text). The value is still bound as a parameter, so this is a correctness/robustness problem rather than injection.

Suggested direction

Escape %, _ (and the escape character) in the bound value and emit a corresponding ESCAPE '\\' clause, so the user's text is matched literally.
