Charles KWON OhJun 1b41384675 fix: CDX mmap + internal node format (BE key-first) — 50K works 
CDX internal node format fix:
- Was: [child LE][recNo LE][key] (NTX-style)
- Now: [key][recNo BE][child BE] (correct CDX format)
- Fixes GoTop/Seek/Scan for large CDX files (50K+ records)

CDX mmap:
- syscall.Mmap on OpenIndex for zero-copy reads
- idx.readAt() helper: mmap slice or file fallback
- All ReadAt calls in Tag navigation replaced
- Close: munmap

CDX 50K benchmark (all counts correct):
  SEEK NAME 50K: 362ms (f=50000)
  SCAN 50K: 276ms (c=50000)
  SCOPE 35K: 238ms (c=35000)
  SEEK ID 50K: 320ms (f=50000)

CDX is slower than NTX due to bit-packed leaf decompression per page.
Cross-read test: 18/18 still PASS.
