Summary

• split rendering-heavy run-view TUI helpers into new src/run_view_render.rs
• keep controller/state and overlay coordination in src/run_view_tui.rs, now re-exporting render-layer APIs used by existing call sites/tests
• wire module declarations in src/main.rs without changing runtime behavior

Validation

• lint: cargo fmt --check
• cargo clippy --all-targets --all-features -- -D warnings
• cargo test -q
