PR Summary

Medium Risk
Mostly adds dev-only tests, but also updates Cargo.lock (including cairo-native rc bump and transitive crate version shifts) which can affect build reproducibility and CI behavior.

Overview
Adds SNIP-35 proposer/validator symmetry coverage by introducing a local validator_accepts predicate and new tests that assert out-of-bounds fee_proposal values are rejected while compute_fee_proposal outputs always pass the same bounds (via deterministic fuzzing with ChaCha8Rng).

Updates apollo_consensus_orchestrator dev-dependencies to include rand/rand_chacha, and refreshes Cargo.lock (notably bumping cairo-native to 0.9.0-rc.6 and adjusting several transitive versions such as ahash, hashbrown, and windows-sys).
