Requested: don't push the operator toward installing wg-easy if they
already have a different mesh VPN (Netbird or Tailscale) running —
detect any of the three first, and only offer a choice when none are
present.
Detection checks wg-easy's own directory (this repo's install marker),
then falls back to checking whether the netbird/tailscale binaries exist
AND their systemd services are actually active — not just installed,
since an installed-but-never-connected client isn't a usable path to the
spare box either. wg-easy takes priority if somehow more than one is
present, since it's this repo's own chain-installable option.
When none are detected, offers a numbered choice: wg-easy (chain-installs
via the existing declare -F guard), Netbird, or Tailscale (both via their
official curl-pipe-sh installers — verified the current URLs against
each vendor's own docs rather than guessing, since a wrong URL here would
be a bad thing to ship). Both third-party options still need a manual
follow-up step this script can't complete unattended (Netbird needs a
setup key from the operator's account, Tailscale needs an interactive
auth link) — the success message says so rather than implying the
install alone finishes the job.
Verified the detection branching against all the cases that matter:
nothing present, only wg-easy's directory, only Netbird active, only
Tailscale active, and multiple present at once (wg-easy correctly wins).
