Add exit node support to the wasm JS bridge:
- Include `exitNodeOption` and `stableNodeID` on each peer in the
notifyNetMap payload so callers can identify which peers are exit
nodes and reference them by stable ID.
- Call `notifyExitNode(stableNodeID)` whenever prefs change, so
callers can track which exit node (if any) is currently active.
- Expose `setExitNode(stableNodeID)` — sets ExitNodeID via EditPrefs.
- Expose `setExitNodeEnabled(enabled)` — toggles the last-used exit
node on/off via SetUseExitNodeEnabled.

Extend ipn.listen to also accept "tcp"/"tcp4"/"tcp6" and return a
TCPListener bound to a netstack gonet.TCPListener. The listener
exposes accept/close/addr like a Go net.Listener and additionally
implements Symbol.asyncIterator so JS callers can write:
for await (const conn of listener) { ... }
The async iterator returns done when the listener is closed (via
errors.Is(net.ErrClosed)) and rejects on any other accept error.
Symbol-keyed properties are set via Reflect.set since syscall/js
only exposes string-keyed Set.
Add ipn.dialTLS(addr, opts?) which dials a TCP connection through
the Tailscale dialer and performs a TLS handshake on top, returning
a JS Conn just like ipn.dial.
WASM has no system root pool, so verification defaults to the
baked-in LetsEncrypt ISRG roots already linked via net/bakedroots.
That covers any tailnet HTTPS endpoint provisioned via
`tailscale cert`. Callers can override with opts.caCerts (PEM) or
bypass entirely with opts.insecureSkipVerify, and override SNI with
opts.serverName.
Marginal binary cost is ~10 KiB on top of the existing ~31.6 MiB
wasm: crypto/tls and the x509 verification path are already pulled
in by control/controlclient and net/tlsdial.
Wire up the userspace networking primitives to the JS bridge so
browser callers can initiate outbound and receive inbound traffic
over the Tailscale network:
- ipn.dial(network, addr) wraps a tsdial UserDial into a JS Conn
with read/write/close/localAddr/remoteAddr.
- ipn.listen(network, addr) wraps a netstack ListenPacket into a
JS PacketConn with readFrom/writeTo/close/localAddr.
- ipn.listenICMP("icmp4"|"icmp6"|"icmp") creates a raw ICMP
endpoint on the underlying gVisor stack and wraps it as a
PacketConn for sending/receiving ping traffic.
To support listenICMP, netstack.Impl gains a Stack() accessor that
returns the underlying *stack.Stack so jsIPN can call NewEndpoint
with icmp.ProtocolNumber4/6.
Binary I/O uses js.CopyBytesToGo / js.CopyBytesToJS to move bytes
across the syscall/js boundary without base64 round-trips.
After 1d93bdce2 ("control/controlclient: remove x/net/http2, use
net/http"), the noise control client uses net/http's Transport with
Protocols.SetUnencryptedHTTP2(true). The nethttpomithttp2 build tag
strips the bundled HTTP/2 implementation from net/http, so at runtime
the control client fails the first register request with "http:
Transport does not support unencrypted HTTP/2" and the wasm never
connects.
Drop the tag so the bundled HTTP/2 ships in the wasm binary.
