Add ADR-016: GPU pipeline future-proofing for cloud gaming 
Ensure today's CPU-first design doesn't block a future zero-copy
GPU encoding path (DMA-BUF → VAAPI/NVENC, sub-5ms encode latency).

Key design constraints:
- FrameSource enum: Cpu and DmaBuf variants (build Cpu now, DmaBuf later)
- FrameEncoder trait: accepts both, encoder picks preferred source
- Pipelined render→encode→send (no synchronous blocking)
- Adaptive frame cadence: OnDamage (desktop) vs Fixed (gaming)
- Damage tracking forks: pixel diff for CPU, Wayland hints for GPU

No GPU code built now -- just trait interfaces that preserve the path.
