What changed
This updates board-driven U-Boot timeout handling so
.board.tomltimeoutis propagated into the U-Boot runtime config.It also keeps the timeout semantics aligned with the existing terminal behavior: the timeout starts when the serial terminal interaction stage begins, not during earlier U-Boot setup, probing, or image staging.
Why
ostool boarddid not honor the configured timeout becauseBoardRunConfigwas not carryingtimeoutintoUbootConfig.That meant board runs silently ignored the timeout value even though direct U-Boot config parsing already supported it.
Impact
Users running
ostool boardcan now configuretimeoutin.board.tomland have it take effect consistently.The countdown starts from the later serial interaction stage, which matches the existing behavior of the terminal runner.
Validation
cargo test -p ostool
