* fix(local): apply score_threshold strictly to match server semantics
The Qdrant server keeps only points whose score is *better* than
score_threshold (strict inequality): a point whose score equals the
threshold is excluded. Local mode used non-strict comparisons, so such
boundary points were incorrectly kept for Cosine/Dot/Euclid/Manhattan.
Fusion and formula post-filters remain inclusive, matching observed
server behavior for those paths.
Includes parametrized regression tests covering all four distance metrics.
* tests: update tests
* tests: update tests to include other query points ways
