Several small issues

[willvincent]

1. Many tests are reporting as risky with no assertions - it looks like newer version of mockery & phpunit don't reliably treat shouldReceive as an assertion, unless you specify the number of times it should be expected.

2. The scout syntax for adding extra conditions via a queryCallback is ignored when building the query:

   // Proper syntax for adding (for instance) a where clause with a scout query:
   User::search($search_term)
       ->query(function ($builder) {
           $builder->where('created_at', '<', '2025-01-01');
       })
       ->get();
   
   // Resulting query is missing the where clause.
   // However this works:
   User::search($search_term)->where('created_at', '<', '2025-01-01')->get();

   Arguably nicer syntax, but should also support the official scout api with a quaryCallback.

3. Only where queries are supported, ideally should also support whereIn() and whereNotIn(), both of which are available on the Laravel\Scout\Builder::class

4. Soft delete support is not properly handled. If soft_delete is enabled in the scout config, the query incorrectly gets a where('__soft_deleted', '=', 0) clause added (by scout internals). Instead we need to replace that clause if it's present with an appropriate whereNull()/whereNotNull() on the softDelete column for the model. This way we can properly handle regular queries, withTrashed and onlyTrashed.
