app.rs:199-214 — menubar handle_key now uses if-let instead of
guarded .unwrap(); dispatch result is no longer swallowed
(errors set status message)
app.rs:391 — Ctrl-Z suspend kill command error now logged
terminal/mod.rs:118,147 — frame-draw + restore flush() now use
.ok() pattern instead of let _ = (more explicit intent)
viewer/mod.rs:967 — menubar.take().unwrap() replaced with
if-let Some(mut mb) pattern
Panic hook write/flush swarrows kept intentionally — stdout
is unrecoverable during a crash; added explanatory comment.
Tests: 1427 pass, zero warnings.
