fix: retire legacy v1 service file after migration switchover

Browse Source 
After migration keeps v2, the old unslugged `nanoclaw.service` (or
`com.nanoclaw.plist`) was only disabled — the unit file stayed on disk.
A `systemctl --user restart nanoclaw` would start v1 instead of v2.

Now the migration removes the old file and symlinks it to the v2 unit,
so the legacy name transparently starts v2. Handles systemd (Linux/WSL)
and launchd (macOS). Idempotent — skips if the symlink already exists.
