Note

Expose LVQ support detection and use it to conditionally report LeanVec reduced_dim in FT.INFO; decouple type check from platform and update SVS tests to include LeanVec4x8 with REDUCE and expected outputs.

• SVS/VecSim internals:
  • Make isLVQSupported() public (vector_index.c/h).
  • VecSim_IsLeanVecCompressionType now only detects LeanVec types (no platform check).
• FT.INFO output:
  • Report reduced_dim only when isLVQSupported() and VecSim_IsLeanVecCompressionType(...) are both true.
• Tests:
  • Extend SVS VAMANA info test to include LeanVec4x8 (with REDUCE), and expect reduced_dim when runtime compression is LeanVec.
