Reflection follow-up: rewrite missing substrate file op-fleet

Missing path: ~/bin/op-fleet Referenced in: FLEET-TOOLS.md line 22: ~/bin/op-fleet item list --vault "Fleet Secrets" Presumed contents: A short shell script that wraps the 1Password CLI op command with HOME=/var/tmp/op-agent, used for listing fleet secrets and vault items. Similar to op-read but passes all args to `op` directly rather than just `op read`. Likely: #!/bin/bash\nHOME=/var/tmp/op-agent op "$@"
