Resolves the two doc-level findings from the cycle-0009 fieldtest
(docs/specs/fieldtest-0009-run-metrics.md), both the same doc pass on
RunReport::to_json's rustdoc:
- spec_gap: the JSON key names and {manifest,metrics} nesting were not on the
public surface — a consumer parsing the JSON (the C18 registry, the deferred
aura run printer) could not author against it from rustdoc alone. Now stated:
keys mirror the struct field names in fixed order, window is a 2-element
[from,to] array, params is an insertion-order object, with a worked sample
object. Ratifies field-name-mirroring as the contract for the C14 face.
- friction: a whole-valued f64 renders without a fractional part (12.0 -> 12),
so one f64 field may appear as an integer or decimal token across runs. Now
documented, with the consumer guidance to parse as a number, never key off
token shape.
Doc-only change; no behaviour change. The sample is a `text` fence (not a
doctest). Verified: RUSTDOCFLAGS="-D warnings" cargo doc -p aura-engine clean;
clippy -p aura-engine --all-targets -D warnings clean; doctests 0.
