Per CTO directive: kill any alias, any shim. R-LWE threshold sig is
named Corona across all live code. Forward-only.
Sweep covers Go + TS + Sol + k8s YAML + JSON + LP markdown + skills
+ docs. Skipped: papers/audits/legal/licenses/blog/HISTORY (immutable
historical record).
Aligns the consensus subobject field with the threshold/corona/consensus/mpc
cascade rename. Forward-only: no alias, no shim.
JSON tag flips from "ringtail" -> "corona" to match the new wire vocabulary;
no clients depend on this field yet (node v1.26.12 service_test.go already
uses Corona — typecheck was the only consumer breaking).
agentic_capnp sub-package was never generated; build-tag dead code referencing it
broke 'go mod tidy' (could not resolve unused phantom import). No-fake policy.
deps: tls v1.0.3 (hkdf.New); go mod tidy
