* Recommend Tailscale when the remote Orca runtime is unreachable
When a remote-runtime connection fails (RemoteRuntimeClientError "Could not
connect to the remote Orca runtime."), append an actionable Tailscale hint to
the user-facing error, branched on whether the endpoint is already on a tailnet:
- Non-Tailscale endpoint: recommend connecting both devices over Tailscale and
pairing with its Tailscale address, with a download link.
- Tailscale endpoint (*.ts.net or 100.64.0.0/10): point at the real causes —
server offline on the tailnet, or Funnel reverted to tailnet-only — and note
that already-paired devices reconnect without re-pairing.
Applied at the desktop transport chokepoint (status probe, in-use calls, and
subscriptions — connection failures reject, so the hint is applied to the thrown
error, not just ok:false responses) and at the web client's connect/timeout
sites. New pure shared helper mirrors withMacTailscaleDnsHint.

* Address review: scope CGNAT hint to IPv4 literals, track re-paired endpoint
- isTailscaleEndpoint: gate the 100.64.0.0/10 check on a full IPv4 literal so
DNS names like 100.64.0.1.example.com no longer get tailnet-specific advice.
- callRuntimeEnvironment: capture the endpoint the queued closure actually used,
so a re-pair between enqueue and dispatch can't append the wrong hint.

* Recognize Tailscale IPv6 endpoints and trailing-dot FQDNs in hint
The remote-runtime Tailscale hint classified IPv6 Tailscale nodes
(fd7a:115c:a1e0::/48) and trailing-dot FQDNs as non-Tailscale, so a
user already reaching their server over Tailscale by IPv6 literal was
wrongly told to 'connect both devices to Tailscale'. Pairing endpoints
can carry bracketed IPv6 literals (resolvePairingEndpoint), so this is
a reachable path. Normalize the extracted host (strip brackets and the
trailing FQDN dot) and add an IPv6 ULA-range check.
