chore(di): timed expressions

[P403n1x87]

Description

We time condition execution to make them interruptible under certain circumstances. In particular, we handle potentially long operations like iterating over arbitrarily-sized collections. This gives a slight improvement over the unbounded case that can lead to long-running condition evaluations.
