feat(l0): RFC-0015 Transport Skins + PNG implementation
...
- png.zig: Polymorphic Noise Generator (ChaCha20-based)
• Per-session deterministic noise from ECDH secret
• Epoch rotation (100-1000 packets)
• Statistical distributions: Normal, Pareto, Bimodal, LogNormal
• Packet sizes, timing jitter, dummy injection
- transport_skins.zig: Pluggable skin interface
• RawSkin: Direct UDP (baseline)
• MimicHttpsSkin: WebSocket over TLS framing
• Auto-selection via probing
• PNG integration for padded frames
Tests: PNG determinism, epoch rotation, WebSocket framing
Next: TLS handshake (utls parroting), DNS skin
