improvement: support brute-force range search for binary sub/superstructure

[862103595]

Improvement Description

BruteForce::RangeSearch<bin1> currently supports binary range search for HAMMING and JACCARD, but it does not yet cover SUBSTRUCTURE or SUPERSTRUCTURE.

This is a capability gap in the binary brute-force range-search path rather than a regression, so the request here is to extend support for these two metrics and add the corresponding test coverage.

Expected Behavior

Binary brute-force range search should also support both SUBSTRUCTURE and SUPERSTRUCTURE.

For identical query/base pairs, range search should return the matching vector with distance 0 when radius is set appropriately, and the corresponding UT coverage should pass.

Scope

• add brute-force binary range search support for SUBSTRUCTURE and SUPERSTRUCTURE
• route binary sub/superstructure range search through the existing binary matcher path
• enable brute-force UT coverage for the new range-search path

Additional Context

PR #1568 implements this extension.
