Optimize WireGuard transport and add global packet buffer pool

WireGuard encrypt 1.8x faster (314 → 556 MB/s), decrypt 1.6x faster
(224 → 362 MB/s) at MTU-sized packets:

- Seal directly into result buffer at offset 16, eliminating the
  intermediate ciphertext allocation (was the largest bottleneck)
- Return PacketResult by value instead of pointer, eliminating a
  heap allocation per processed packet on the decrypt path
- Single now() call per encrypt instead of three

Add pktkit.AllocBuffer/FreeBuffer as a global sync.Pool for ~1500-byte
packet buffers shared across NAT, WireGuard, and other subsystems.
Migrate NAT from its own local pool to the global one.
