validate zero limit at the beginning in the VDBE program

core/vdbe: Fix MakeRecord affinity handling
...
The MakeRecord instruction now accepts an optional affinity_str
parameter that applies column-specific type conversions before creating
records. When provided, the affinity string is applied
character-by-character to each register using the existing
apply_affinity_char() function, matching SQLite's behavior.

Simplify ORDER BY sorter column remapping
...
In case an ORDER BY column exactly matches a result column in the SELECT,
the insertion of the result column into the ORDER BY sorter can be skipped
because it's already necessarily inserted as a sorting column.
For this reason we have a mapping to know what index a given result column
has in the order by sorter.
This commit makes that mapping much simpler.
