style: cargo fmt --all to satisfy CI fmt check

CI started failing on rustfmt 1.88 because recent edits left a few
multi-arg expressions/array literals over rustfmt's width budget.
Reformatted in eros-engine-llm/model_config.rs (fixture test arrays),
eros-engine-server/main.rs (persona seeder reads), and
eros-engine-store/persona.rs (upsert_genome guard) to match.
