Summary

• move the generic run-view TUI controller/state, key mapping, overlays, and status-bar rendering helpers out of src/main.rs into new src/run_view_tui.rs
• keep existing call sites unchanged via module imports so runtime behavior remains the same while reducing main.rs surface area
• preserve existing test coverage and public crate-level wiring used by fleet/runtime/tui modules

Validation

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