描述

We have a few p.recovery.pto * 3 calculations scattered throughout the codebase. These seem to be used for calculating timeouts. It would be nice to have this logic extracted into its own function.

研究方向
The issue points to three specific locations in quiche/src/lib.rs (lines 8452-8455, 3233, 4706) where `p.recovery.pto * 3` is used. A new function should be created, perhaps `fn pto timeout(&self) > Duration` in the recovery module, and the scattered calculations replaced with calls to this function. Ensure the function is documented and consider adding a unit test for the timeout calculation. No existing PRs or assignees were found, so the work is available.
