Subject: feat(vpn): wireguard config import for the NM migration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

scripts/import-wireguard-configs.sh imports the seven Proton configs into NetworkManager with autoconnect forced off. Each config stages through a wgpvpn.conf temp copy (NM's import name must be a valid interface name; several config names exceed the 15-char limit) and is renamed by the UUID parsed from the import output, so a stray same-named connection can't be hit. A leftover wgpvpn connection — a run that died between import and rename, autoconnect still armed — makes the script refuse to run. 10 tests over a fake nmcli; velox migration verified (all seven wireguard, autoconnect no). The tunnels spec is implemented: all six phases shipped.

+# Fake nmcli for the import-wireguard-configs tests.
+#
+# Behavior is driven by env vars set by the test harness:
+#   FAKE_NMCLI_LOG    file every invocation's args are appended to (one line
+#                     per call; for imports the staged file's basename and
+#                     content hash context are visible in the args)
+#   FAKE_NMCLI_NAMES  newline-separated connection names returned by
+#                     `nmcli -t -f NAME connection show`
+#   FAKE_NMCLI_IMPORT_OUT  override for the import command's stdout
+#                     (default: the real NM success line with a per-call
+#                     deterministic UUID)
+#   FAKE_NMCLI_MODIFY_RC   exit code for `nmcli connection modify` (default 0)
+#
+# Import calls also copy the staged file into $FAKE_NMCLI_LOG.d/ so tests can
+# assert the temp copy was named wgpvpn.conf and carried the right content.
