Subject: [PATCH] fix(wake): wake-auto-t3 logs the signal that stops it

On SIGTERM or SIGINT the supervisor aborted and returned 0 without a log line, so a signal sent by anything other than the service manager looked like a normal stop in the journal. It now logs the signal name once before shutdown. Closes #187.

 ## Unreleased
 
+- `swarmail wake-auto-t3` logs `received SIGTERM; stopping` (or `SIGINT`) when it receives the signal, so a
+  signalled stop no longer looks like a silent exit 0 in the journal.
+
 - The provider comparison covers T3 Code 0.1.1 and the reviewed nightly's terminal commands,
   pull-request lookup limits and automatic-notice snooze behavior.
