Function await_commit_recovery 

pub async fn await_commit_recovery(subject: &str, log: impl Fn(&str)) -> bool

Wait for system commit to recover above RESUME_FLOOR_MB, probing with exponential backoff (BACKOFF_START → BACKOFF_CAP). Returns true once recovered, or false if OOM_RELAUNCH_DEADLINE elapses first (the caller then gives up gracefully). log is the launcher’s logger, threaded in so the wait is observable in the launcher log. subject names whatever is being waited on for the two terminal log lines (“relaunching {subject}” / “giving up {subject} relaunch”) — this function is shared by the host-OOM wait (subject: "host") and the srv-OOM wait (subject: "srv", SPEC_MEMORY_PRESSURE_SUPERVISION’s srv counterpart). Hardcoding “host” here made the srv-OOM wait’s log misleadingly claim it was relaunching the host during an actual srv-OOM incident — reagent P1 on PR #2206.
