validate_dense_vector and validate_multivector checked isnan, so NaN was rejected at write time while +-inf slipped through, despite both docstrings claiming parity with the server. Once stored, an infinity corrupts silently: * COSINE normalises it into NaN, and the corrupted point then sorts to the top with a NaN score, ahead of an exact match; * DOT and EUCLID score it inf; * an inf among a sparse vector's values scores inf. Check isfinite over the float32 values that actually get stored, so a value that is finite as a Python float but not as float32 (1e40) is caught as well, and keep numpy's overflow warning out of the user's output. Query-time checks in distances.py and multi_distances.py still reject only NaN; they are left alone here to keep the change reviewable.

Sparse write validation rejects the same values, while sparse query validation continues to accept infinity. Tests cover rejected writes, query behavior, retained vectors after rejected rewrites, and write atomicity.

- Around line 31-33: Adjust validate_sparse_vector so query validation rejects
NaN values without rejecting infinities or float32-overflow values, while
preserving finite-value validation for write paths. Introduce separate
query/write validation or an explicit write-validation mode, and add a
regression test covering sparse queries with infinities and overflow values.

validate_sparse_vector is called on query paths too (search inputs, recommend positives/negatives, sparse distance queries), so widening it to reject +-inf changed query-time behaviour that this PR does not intend to touch. It is restored to the NaN-only contract, and a new validate_sparse_vector_at_write adds the finite check for stored values; upsert/persistence call sites switch to it. Also add docstrings to every function touched by this PR (CodeRabbit docstring coverage check), and pin the unchanged query-time behaviour with test_sparse_query_paths_still_accept_infinity.
