Preserve leading zeros and literal CSV values in JSON

Values such as 00123, 12.50, false and null stay quoted so conversion does not silently reinterpret them.

The first record is the header. Spaces are data; blank and uneven rows are not repaired.

Every cell becomes a JSON string. Headers keep exact spelling and order; malformed quoting and unequal row widths are rejected.
