+Runtime Equivalent to Shuffle.
+
+Performs element-wise table lookups using runtime indices.
+Each element in the indices vector selects an element from the table vector.
+The indices are automatically masked to prevent out-of-bounds access.
+
+This operation is hardware-accelerated on most platforms when using 8-bit
+integer vectors. For other element types or unsupported vector sizes, it
+falls back to software emulation.
+
+Inputs:
+- `table`: The lookup table vector (should be power-of-2 size for correct masking).
+- `indices`: The indices vector (automatically masked to valid range).

+Returns:
+- A vector where `result[i] = table[indices[i] & (table_size-1)]`.
+
+Operation:
+
