fix(core): compute decimal arithmetic with i256 and checked ops Bounding inferred precision at 38 lets previously rejected expressions plan, but evaluation still used unchecked i128 kernels. Two values of scale 20 square their raw representation to 10^40 when multiplied even though the answer fits, and 9e37 + 9e37 exceeds i128, so evaluation could panic or wrap to a wrong-signed value. Multiply and divide now compute through i256 with checked operations; add and subtract use checked i128. A result that does not fit the inferred Decimal128(38, s) becomes null instead of panicking or wrapping. Division inference also keeps at least the divisor's scale. The shared cast path casts the divisor to the result type, so a bounded scale below the divisor's would truncate its fraction and turn 1 / 0.5 into a division by zero. Integer digits give way instead; quotients that no longer fit decode to null through the checked kernel. Adds value-level regression tests through the Series cast + kernel path for large-scale intermediates, fractional divisors, and overflow.

fix(parquet): emit no batches from fully-deleted count-only reads When positional deletes remove every row, count_only_stream computed n == 0 but still emitted a 0-row batch. stream_parquet already avoids that for empty row groups because downstream sinks treat any received batch as data; an iceberg writer would land an empty snapshot. Return an empty stream when n == 0 and cover the fully-deleted case in the regression test. Also give the test its own per-run temporary directory so parallel test processes cannot overwrite or delete each other's parquet file.

chore!: Upgrade S3 client library (#7622) ## Changes Made Upgrade the S3 client library such that we can delete a bunch of dependencies related to an older `http 0.2` library we were unnecessarily pulling in. Also helps upgrade a bunch of other dependencies that we are having Dependabot warnings about.
