check-compactlisted

Run your session status script (e.g. `bash tools/session-status.sh`) to get the current ctx%. Report based on ctx% value: - ctx < 40%: "Context light - no compact needed (ctx=X%)" - ctx 40-69%: "Context moderate (ctx=X%) - compact if starting a large task" - ctx >= 70%: "Context heavy (ctx=X%) - run /end-session then /compact now" - No data (script absent or no output): fall back to counting exchanges: if >15, warn; otherwise clear. One line only. No preamble. No explanation.
