Charles KWON OhJun 8f354ae24d perf: gengo RDD optimization — reduce VM overhead per operation ...

REPLACE (gen_cmd.go):
- Cache area.(*dbf.DBFArea) once per command (was N times for N fields)
- Remove _fi >= 0 check (FieldIndex returns -1, PutValue handles it)
- Reduces type assertions from N+1 to 2

GO/SKIP (gen_cmd.go):
- Literal integer parameters emit directly (no Push/Pop stack ops)
- GO 5 → _area.GoTo(uint32(5)) instead of Push(5) → Pop → AsNumInt
- SKIP -1 → _area.Skip(-1) instead of Push(1) → Negate → Pop

Benchmark impact (50K, ext4):
- SEEK random: 138ms → 121ms (12% improvement)
- DUPKEY scan: 41ms → 37ms (10% improvement)
- DELSCAN: 32ms → 28ms (13% improvement)

82/82 stress test PASS. 14 packages ALL PASS.
