Cycle 1 of the World/C21 milestone (#165): `aura run <blueprint.json>` loads a
serialized C24 signal blueprint, wraps it in the existing Stage-1-R run
scaffolding via a shared seam extracted from run_stage1_r, compiles + bootstraps
+ runs, and emits a RunReport whose RunManifest carries a new Tier-1-optional
topology_hash (SHA256 of the canonical blueprint form, #158 anchor).
A serialized blueprint is a SIGNAL (sinks/brokers/data/clock out of the
round-trippable set, C24), so aura run WRAPS the loaded signal in a runnable
harness — the same wrap the Rust path does, shared as one function so
"bit-identical to the Rust path" is the same seam over the same signal. The
round-trip bit-identity is already proven (blueprint_serde_e2e.rs); cycle 1
lifts it to the CLI + adds topology_hash.
Boss-signed on a grounding-check PASS: all six load-bearing current-behaviour
assumptions ratified by named green tests (blueprint_from_json, the bit-identical
round-trip, the run_stage1_r compile/bootstrap/run path, RunManifest's Tier-1
optional-field pattern, canonical blueprint_to_json, window_of). Derived
wrapping decision recorded on #165. sha2 enters under the C16 per-case
dependency review (SHA256 user-settled).
