fix: SDWAN TUN device lifecycle + stability
...
Key fixes:
- SDWAN config: use absolute path /root/.openclaw/workspace/inp2p/sdwan.json
- Client: register handlers BEFORE ReadLoop (race condition fix)
- Client: make ensureTUNReader non-fatal on error
- Client: fix TUN device conflict between ip tuntap add and ioctl
- Client: fix panic on empty TUN read (n==0 check)
- Build: static binary with -extldflags=-static for glibc compatibility
Verified: hcss(10.10.0.3) <-> i-6986(10.10.0.2) ping 5/5, 0% loss, 44ms

feat: raw binary SDWAN data plane + EncodeRaw + TUN close-on-stop
...
- protocol: add SubTunnelSDWANRaw subtype + EncodeRaw() for zero-copy IP packets
- client: tunReadLoop sends raw frames (no JSON/base64 overhead)
- client: SubTunnelSDWANRaw handler strips header and writes directly to TUN
- client: Stop() closes TUN file FIRST to unblock tunReadLoop
- server: SubTunnelSDWANRaw handler parses IPv4 src/dst from raw packet
- server: RouteSDWANPacket forwards as raw frame to destination
Verified: hcss(10.10.0.3) ↔ i-6986(10.10.0.2) ping 3/3, 0% loss, 46ms RTT

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
