refactor[fsst]: take VarBinView directly, decide offset width upfront Replaces the `ArrayAccessor::with_iterator` abstraction in `fsst_compress` and `fsst_train_compressor` with direct `&VarBinViewArray` arguments. A single preemptive pass sums view lengths and counts non-nulls; the codes-offsets width is picked upfront against the FSST worst-case bound `2 * total + 7 * non_null <= i32::MAX`, dispatching to a monomorphized `compress_views::<O>`. `&VarBinArray` callers (bench/test fixtures) go through new `fsst_compress_varbin` / `fsst_train_compressor_varbin` helpers gated behind `_test-harness`. Follow-up to #7853 addressing Robert's review feedback on #7833. Co-Authored-By: Claude <noreply@anthropic.com> Signed-off-by: mprammer <martin@spiraldb.com>
