The decentralization stack overcomplicated the project. Removed:
internal/pow, internal/smt, internal/checkpoint, internal/bft,
internal/lightnode, cmd/lightnode, relay gossip/checkpoint/proof/BFT
endpoints, their docs, vectors and the blake3 dependency.
Kept: WebSocket streaming on the relay, the full protocol v1 object set
including DelegationClaim (0x07) and KeyRotation request/confirm
(0x08/0x09) with chain resolution in verify.Graph, TrustedIssuers,
batch fetch, stable cursor pagination, per-type metrics.
INV-1 reverts to its original form: the relay holds no keys again.
Everything removed remains reachable at commit 20cc52c.
