Charles KWON OhJun 7fec4ce150 perf: 50K benchmark — Harbour vs Five on ext4 ...

50K records benchmark on native ext4 (home directory):
- APPEND 50K: Five 140ms / Harbour 61ms (2.3x)
- INDEX 50K:  Five 31ms / Harbour 6ms (5.2x)
- SEEK 50K:   Five 142ms / Harbour 23ms (6.2x)
- SCAN 50K:   Five 35ms / Harbour 5ms (7x)
- PACK 50K:   Five 19ms / Harbour 16ms (1.2x)

All within acceptable Go vs C overhead (2-7x).
PACK nearly identical. APPEND close (2.3x).

Known issue: 3-level NTX bulk build has separator duplication
at interior→root level (count=50083 vs 50000).
Does not affect correctness for <= 2-level trees (100 records OK).
