claude 34ff539143 feat: measurement run verb — shape-dispatch aura run on blueprint output
Phase 3 of the Stratification milestone (contract C28). `aura run` now
shape-dispatches on the loaded blueprint: a `bias` output takes the
existing strategy path (wrap_r + R evaluation), byte-identical; a
blueprint that declares taps but exposes no `bias` runs bare via the new
`run_measurement` (bootstrap, run, drain the declared taps) with no
SimBroker, no risk executor, and no per-cycle equity/exposure/r
recorders; a blueprint exposing neither is refused. This gives the
measurement layer its own run verb and removes the O(cycles) recording
retention (the measured ~2 GB peak RSS over 12y UK100 M1) the mandatory
R scaffold imposed on a measurement-shaped run.

A new `MeasurementReport { manifest, taps }` (aura-engine::report, beside
RunReport) is the stdout/record shape — no R metrics, since a bare run
has no broker. The manifest's `broker` carries an interim "measurement"
sentinel; the honest `Option<String>` model is deferred to the #147
metric-genericity block, keeping this phase #147-free and the
strategy-path C18 goldens byte-identical.

`run_signal_r` is untouched (the tap machinery is duplicated into
`run_measurement`, not extracted). The measurement arm's closed-blueprint
guard uses `signal.param_space()` rather than `blueprint_axis_probe`,
which welds wrap_r and would panic on a no-`bias` signal.

//! Run summary metrics + the reproducible run manifest (C18 / C12): the
//! `(manifest, metrics)` pair a run produces "from day one". The metrics are a
//! **post-run pure reduction** over a run's recorded streams — a node cannot
//! reduce end-of-run (C8 caps a node at one record per `eval`, with no terminal
//! `eval`), so the World drains its recording sinks after [`Harness::run`](crate::Harness::run)
//! and folds them here. Output is canonical JSON (C14): the schema is tiny,
//! closed, and flat. `to_json` renders via serde (the report types derive it,
//! cycle 0029) — the same encoder the run registry uses, so a record's stdout
//! and on-disk shapes coincide.
