perf: CDX zero-alloc internal node seek — SEEK 45% faster
Internal node traversal: read directly from mmap/buf slice
- No DecodeIntKeys allocation (was nKeys+1 IntKeyEntry structs)
- No key byte slice copy (compare directly against buf)
- Big-endian child/recNo read inline
CDX 50K benchmark:
SEEK NAME: 362ms → 199ms (45% faster)
SEEK ID: 320ms → 184ms (42% faster)
SCAN: 14ms (unchanged — leaf cache handles this)
SCOPE: 20ms → 14ms
Harbour comparison:
SEEK: 27ms (Harbour) vs 199ms (Five) = 7.4x
SCAN: 6ms (Harbour) vs 14ms (Five) = 2.3x
CDX cross-read: 18/18 PASS.
