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.

Examples:

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.
