Under tailscaled --tun=userspace-networking (no TUN device — the default
in unprivileged containers), processes cannot dial tailnet addresses at
all: inbound connections are proxied to loopback by tailscaled, but
outbound 100.64.0.0/10 dials have no route. omarchy-send could receive
on such boxes but never send, probe, or discover over the tailnet.
New internal/tsproxy auto-detects this: when no local interface carries
a tailnet address but a SOCKS5 proxy answers at localhost:1055 (the
conventional --socks5-server address), tailnet-bound connections route
through it. LAN traffic is never proxied; explicit HTTPS_PROXY/
HTTP_PROXY/NO_PROXY win over detection, restoring the env-var support
the custom transports had silently dropped.
Also guard NotePeer against the loopback trap the same proxying causes:
inbound registers all appear to come from 127.0.0.1, and recording that
over a peer's routable address made a TUI "send" loop back to our own
receiver while looking delivered.
Live-verified from an omaterm container (userspace tailscaled): headless
send discovered and messaged a tailnet peer with no env vars set.

runHeadlessSend only ran multicast discovery, so `--to <alias> --message`
could not reach a peer that is only routable over the tailnet (or another
subnet), even though the TUI and quick-send paths could via watchRemotes.
Start the same watcher in the headless path: known peers from config plus
online Tailscale peers are unicast-probed, the probe handshake records the
peer, and FindPeer picks it up like any multicast discovery.
Verified live against a tailnet-only peer (different subnet, DERP-relayed):
discovered and message delivered. TestFindPeerViaProbe covers the
composition Probe -> NotePeer -> PeerFound -> FindPeer.

Multicast only finds peers on the same LAN. Reach off-LAN boxes by probing
them directly over unicast (works over any routable address; Tailscale is the
easy, secure choice):
- discovery.Probe: unicast POST /register (https->http fallback) with a two-way
handshake, so send and receive both work; offline peers age out.
- internal/tailscale: Peers() shells `tailscale status --json` for online peers.
- config.KnownPeers: persisted manual remotes.
- main.go: watchRemotes goroutine probes knownPeers ∪ tailscale peers every 10s,
in both the normal TUI path and quick-send.
- TUI: `+` on Devices opens an add-remote modal (host/IP/Tailscale name).
- install.sh: interactive local/remote install prompt; remote mode locks port
53317 to the Tailscale interface (ufw), with container/userspace-networking
detection. README documents remote devices.

Two related additions for using omarchy-send beyond the focused TUI:
Headless send (no TUI / no TTY) — for scripts, cron, SSH sessions:
omarchy-send --to "<alias>" --message "<text>" [--send-pin N] [--wait 15s]
Resolves the peer by alias over multicast (discovery only, not the HTTP
receiver, so it co-exists with a running instance), sends, prints a
one-line result, and exits non-zero on not-found / failure. New
discovery.FindPeer/Snapshot and client.SendMessageSync (returns the error
directly, incl. ErrPinRequired).
Bugfix surfaced by the above: the official LocalSend client answers a
message prepare-upload with HTTP 204 No Content (the text rides in the
preview field, nothing to upload). prepareUpload only accepted 200, so
message sends to official peers failed with "prepare-upload status 204"
in BOTH the new headless path and the existing TUI. Now treats 204 as
success (empty response).
Desktop notifications: a running receiver raises a notify-send
notification on an incoming message or file offer, so mako shows it on
Omarchy/Hyprland even when the TUI isn't focused. New internal/notify
(best-effort; self-disabling on headless boxes with no notify-send /
session bus). Off-switch: --no-notify flag, cfg.NoNotify, and a Settings
'n' toggle wired to a live atomic gate via Controller.SetNotify so it
takes effect without a restart.
Tests: discovery/find_test, client/message_sync_test,
client/prepare_204_test, app/events_test. Race-clean.
