pub const FLEETS: &str = "fleets";Expand description
Fleet definitions: <mur_home>/fleets/<name>/fleet.yaml, plus the
operator’s .stopped kill-switch and the daemon’s .last_run stamp.
Configuration, not run state — deliberately absent from
RUN_STATE_DIRS. A run that could write here could rewrite its own
fleet’s members, limits and HITL pre-approvals, or clear its own
kill-switch.
