perf(map): reuse existing values and defer creation with size hint

Optimize map decoding with two complementary changes:
- Reuse existing map values instead of allocating new ones (typed decode: 14-16% faster,
  60% less memory, ~99% fewer allocs)
- Defer map creation until first block and use block length as size hint (generic decode:
  up to 7% faster, 15% less memory)
