Juan DenisandClaude Opus 4.8 7cf8d4e18a feat(remote-access): NAT-traversing WireGuard tunnels to expose private services ...

Self-hosted tunneled reverse proxy: a service on a NAT'd host (e.g. a home
Jellyfin box) gets a public HTTPS hostname with no port-forwarding, by pairing
two agents over WireGuard. Implements Phases 0-3 of docs/REMOTE_ACCESS_ROADMAP.md.

Agent (Go):
- new internal/wireguard package: Manager interface + kernel backend (wg/ip)
  and a userspace netstack backend (wireguard-go + gVisor) so Windows/macOS
  peers need no driver/admin; in-process keygen returns only the public key
  (private keys never leave the host)
- wireguard:keygen/interface/peer/status/forward/unforward + firewall
  :allow_port/:deny_port commands; wireguard + firewall capability probes
- TCP forwarder (tnet.ListenTCP / net.Listen -> dial localhost) carries
  traffic to the real service behind a netstack peer

Backend (Python):
- Tunnel + ExposedService models; tunnel_netutil (subnet allocator, health);
  tunnel_broker_service (keygen->up->peer->verify, firewall open, reconcile-on-
  reconnect); tunnel_publish_service (forward -> nginx -> DNS -> auth -> cert)
- nginx remote-upstream vhost (WebSocket + proxy_buffering off)
- /api/v1/tunnels CRUD + /<id>/services publish/unpublish
- panel-authoritative reconcile hooked into the agent gateway on reconnect

Frontend (React):
- Remote Access page (tunnels + exposed services, status, teardown) and an
  "Expose a Local Service" wizard; new services/api/tunnels.js

Verified: go build (win/linux) + vet + go tests (forwarder + no-leak parsers);
py_compile + pytest (netutil, reconcile, nginx template); create_app boot;
eslint + npm run build. Live multi-host run pending.
