The clap help promised "persists each member's/OOS window's taps" and the chart
NotFound hint recommended `aura sweep --trace`, but every blueprint-mode arm
discarded the flag (run_blueprint_sweep's `let _ = persist`, the --real sugar's
persist_taps: vec![]) — the surface advertised trace-recording the code dropped.
Refuse --trace up front on both verbs (exit 2, "--trace is not yet available on
<verb>; see #224"), mirroring the existing aura run / aura mc refusals; drop the
false promise from the two help lines and the chart NotFound hint. Delivering
per-member trace-writing is deferred to #224.
Collateral: four synthetic-sweep tests that used --trace as a family-name handle
move to --name (same handle, still accepted); the walkforward name/trace test now
pins the up-front #224 refusal.
Workspace suite green (62 groups / 0 failed), clippy -D warnings clean.
