Commit Message

connection: fix data race in context watchdog

The context watchdog accessed the future object directly, which could
be released concurrently when the response arrived. This caused a
data race that manifested as "unlock of unlocked mutex" panics under
concurrent context cancellation.

The watchdog now captures the wait channel and request ID before
starting the goroutine, and uses fetchFuture to safely access the
future only if it still exists in the connection's internal queue.

Follows #595
