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.

Previously the advertised device name defaulted to the machine hostname.
Since the alias is broadcast in plaintext over multicast to the whole
subnet every few seconds while the TUI is open, that leaks the hostname
to anyone on the network — a privacy problem on a laptop joining
untrusted Wi-Fi (the reason LocalSend randomises its aliases).
Now first run generates a random "Colour Object" name from public-domain
word lists (e.g. "Crimson Quasar"): 56 colours x 44 celestial objects =
2464 combinations. It is generated once and persisted, so a device keeps
the same name across restarts. The hostname is still carried in
DeviceModel, and the alias remains overridable via --alias or Settings.
Word lists are original and use only generic colours and public-domain
astronomy terms, so there is no copyright or trademark exposure.
