Summary

• move the fleet manager runtime loop and its control/selection helpers from src/main.rs into src/fleet_runtime.rs
• preserve fleet manager behavior and existing keyboard/control contracts while reducing another large concentration point in src/main.rs
• keep the extraction covered by the current fleet runtime tests with strict clippy enforcement

Validation

• cargo test
• cargo clippy --all-targets --all-features -- -D warnings
