Fix: builder wherein

[AxiosLeo]

Note

High Risk
Changes core WHERE binding for IN and JSON IN-style operators across all query paths; wrong binding previously caused silent empty results in transactions, so behavior changes are intentional but affect every consumer using these conditions.

Overview
Fixes a silent data bug where whereIn / whereNotIn and related IN filters returned no rows (or updated/deleted nothing) inside transactions, while the same queries worked outside transactions.

The SQL Builder now emits one ? per list element and binds flat scalars (via _buildArrayPlaceholders) instead of a single placeholder bound to a nested array. That aligns conn.query and conn.execute (prepared statements on the transaction path).

The same expansion applies to JSON path IN / NOT IN, CONTAIN / NOT CONTAIN, and OVERLAPS / NOT OVERLAPS. Comma-separated strings for IN are split and trimmed like arrays; empty strings still throw like empty arrays.

Release 0.15.2 adds CHANGELOG.md, bumps package/CLI version, and adds regression tests (unit, mocked transaction execute, and a MySQL feature scenario).
