You can now pause a thread without setting a wake-up time.

The existing pause behavior stays exactly the same — a customer reply brings the thread back, a linked Linear issue moving to Done fires Close the Loop. The only thing that changes is you no longer have to pick a date when you don't have one. Choosing "indefinitely" tells Plain: park this until something actually happens, not until an arbitrary timer fires.

This is the right move for threads that are blocked on engineering, waiting on a third-party vendor, or on hold for a reason that has no natural deadline. Instead of re-snoozing every few days to keep the thread off your queue, you pause once and let the trigger do the work.
