fix(query): preserve full maxDistance precision in VECTOR_RANGE query

Replace %.1f format specifier with %s to avoid truncating user-provided
maxDistance values. Previously, maxDistance(0.01) would produce
"VECTOR_RANGE 0.0" (matching nothing) and maxDistance(0.05) would
produce "VECTOR_RANGE 0.1" (doubling the intended radius). Add unit
test verifying sub-decimal precision is preserved.
