The amd64 link of libnumkong.so was segfaulting under the experimental lld 1:18.0-59~exp2 from Noble universe after 91c08cc widened nk_shared symbol visibility, pushing the LTO unit past what that lld release can handle. Switch the JNI Linux job to mold via -fuse-ld=mold for both shared and module link steps. mold ships in Noble main, supports the LLVM gold plugin needed for clang LTO, and avoids pinning a separate apt source.
The non-multi branch of `get_typed_vectors_for_keys` pre-allocated a 2D ndarray of shape (keys_count, dims) and ignored the return value of `index.get(...)`. Missing keys left rows of uninitialized memory that were then returned to Python — a bug with security implications, as heap residue could leak through `Index.get`. Switch to a single-allocation backing 2D array plus per-key 1D views into its rows; missing keys yield `py::none()` instead of leaking the uninitialized row. The data path stays a single allocation regardless of which keys are present, matching the docstring contract on `Index.get` (`Returns None, if one key is requested, and its not present`; `If multiple keys are requested, composes many such responses into a tuple`). Pin the contract with a regression test covering single-missing, single-present, mixed batches, and post-remove lookups for both multi and non-multi indexes.

Previously, the usearch_windows_x86_X.Y.Z.tar package in each release contained a 64-bit binary library, despite being labeled as 32-bit base x86. Closes #665
