MC uses SIGWINCH→self-pipe→select(stdin+pipe) for resize detection.
In safe Rust (#![deny(unsafe_code)]), the equivalent is polling stdin
with a 200ms timeout via rustix::event::poll. This wakes the main loop
every 200ms even without key input, allowing terminal size check and
full redraw on resize. Same result as MC's signal-driven approach
without requiring unsafe signal handlers.
Previously the event loop blocked indefinitely on events.next() —
terminal resize was only detected on the next keypress.
