Invalidate precomputed_table after add and handle k=0 in TopKHeap

- Clear precomputed_table in add_batch() alongside fastscan_codes,
  preventing stale table from being used after new vectors are added.
  Matches the invalidation already done by merge_from().

- Guard TopKHeap::push against k=0 to avoid panic on empty heap access.

- Add test_precomputed_table_invalidated_after_add regression test:
  build_precomputed_table → add → assert cleared → rebuild → search
  finds vectors from both batches.
