copytrade.py moves out of archive/ + Fly health check (watchdog layer 1)

The execution engine was load-bearing from archive/ — the one thing in
there that wasn't retired. Now at repo root next to copybot.py; the two
archived scripts that imported it as a sibling get a parent-path shim.
fly.toml gains an http /health check so Fly restarts a dark machine
(self-heal); the notify half is the GH Actions watchdog (next commit).
