feat: SDWAN data plane + UDP punch port fix + TUN reader
SDWAN:
- protocol: add SDWANConfig/SDWANPeer/SDWANPacket structs, MsgTunnel type
- server: sdwan.go (JSON file store), sdwan_api.go (Get/Set/broadcast/route)
- server: push SDWAN config on login, announce peer online/offline events
- server: RouteSDWANPacket routes TUN packets between nodes via signaling
- client: TUN device setup (optun), tunReadLoop reads IP packets
- client: handle SDWANConfig/SDWANPeer/SDWANDel push messages
- client: apply routes (per-node /32 + broad CIDR fallback)
UDP punch fix:
- nat/detect: capture LocalPort from STUN UDP socket for punch binding
- client: pass publicPort + localPort through login and punch config
- coordinator: include PublicPort in PunchParams for both sides
- protocol: add PublicPort to LoginReq and ReportBasic
Other:
- server: use client-reported PublicIP instead of raw r.RemoteAddr
- server: update PublicIP/Port from ReportBasic if provided
- client: config file loading with zero-value defaults backfill
- .gitignore: exclude run/, *.pid, *.log, sdwan.json
- go.mod: add golang.org/x/sys for TUN ioctl
