Query builder generates invalid SQL for empty in filters

# Query builder generates invalid SQL for empty `in` filters ## Bug Passing an empty array to an `in` filter generates PostgreSQL syntax such as: ```sql select * from public.users where id in (); ``` PostgreSQL rejects `IN ()` with a syntax error. Tuple filters have the same problem: ```sql where (id, version) in () ``` ## Reproduction ```ts new Query() .from('users', 'public') .select() .filter('id', 'in', []) .toSql() ``` This is reachable in Studio's vault helpers. `getDecryptedParameters()` passes `Object.values(paramsToBeDecrypted)` to `getDecryptedValues()`. For wrappers with no encrypted parameters, that value is an empty array and the generated vault query is invalid. ## Expected Membership in an empty set should produce a valid always-false predicate, so selects return no rows and updates or deletes remain safe no-ops.
