v2 - 2026-04-22 - Entity search and field value management

Search entities Added support for filtering by custom fields in filter.fields. Text, number, date, single-select, and multi-select custom fields are supported with type-specific operators (contains, eq, id/name, any/all)
Search entities Changed return.fields to accept "all" or "default" as string values, in addition to an array of field names
Create field value Added endpoint to create a new value (option) for a select-type field (SINGLE_SELECT, MULTI_SELECT, TAG). If color is omitted, the next available color is assigned automatically
Update field value Added endpoint to update an existing value on a select-type field. Only provided fields are updated; omitted fields remain unchanged
Delete field value Added endpoint to delete a value from a select-type field. Use force=true to unset the value from all entities, or replaceWith to reassign assignments to another value (the two parameters are mutually exclusive)
