Charles KWON OhJun 5b378318a0 perf: RTL optimization — cached WA, spaces pool, stack-alloc fmt_int64 ...

rdd.go:
- getWA() cached type assertion (avoid repeated interface check)
- waCache stores last WA pointer → O(1) for repeated calls

strings.go:
- spacesCache[257]: pre-built space strings for pad sizes 0-256
- spaces(n) returns cached string (no Repeat allocation)
- PadR/PadL use spaces() for fill=" " (most common case)
- Str() uses spaces() for right-padding

missing.go:
- fmt_int64: stack-allocated [20]byte array (was heap make([]byte))
- Reverse iteration (no prepend overhead)
- PadC uses spaces() for left/right padding

Benchmark (ext4, home dir):
  10K APPEND: 28ms → 26ms (Harbour 27ms!)
  50K APPEND: 130ms → 113ms (13% improvement)
  50K SCAN: 24ms → 23ms
  50K DUPKEY: 42ms → 35ms (17% improvement)
  CDX SCOPE: 12ms → 10ms (17% improvement)

82/82 stress PASS. 14 packages ALL PASS.
