ChainedCall.pre_states: Vec<AccountWithMetadata> becomes pre_state_refs: Vec<AccountId>. A calling program no longer supplies the concrete account value (or an is_authorized claim) for an account it hands to a chained call — it only names which account, and the protocol (sequencer for public transactions, host driver for privacy-preserving ones) resolves the real, currently-tracked value itself before invoking the callee. This removes two things simultaneously: the burden on guest programs to predict another call's outcome before it happens (the calling program previously had no reliable way to know it), and the ability to supply a stale or entirely fabricated account value at all. The malicious_injector/malicious_launderer guest programs and malicious_authorization_changer, which existed specifically to demonstrate that forgery, are deleted — the attack they showed is now a compile-time impossibility rather than something caught after the fact by a runtime check. The privacy circuit itself (execution_state.rs) needed no logic changes: it never trusted a caller-supplied pre-state in the first place, only the callee's own proven echo against its internally tracked state. The public path already had the tracking map it needed (state_diff); the privacy host driver gained one (materialized_state), plus first-sighting position tracking so a chained call's private-PDA authorization can be verified the same way the circuit derives it internally. Regenerates all lee_core/lez guest artifacts and the prebuilt sequencer db fixture via `just build-artifacts`, required since ChainedCall's shape is part of the proven wire format.
