Claude 8233392871 Fix client timeout propagation and add operation retry logic
The client library had several issues preventing operations from completing
in the simulation:

- toastyfs_register_events discarded the computed timeout instead of
  returning it to callers, so clients never woke up on schedule
- random_client_tick ignored the timeout parameter entirely
- deadline_to_timeout truncated sub-millisecond values to 0 instead of
  rounding up, causing busy-wait loops
- The server didn't reset the heartbeat timer after completing a view
  change, so followers would immediately timeout again
- The client's DELETE handler didn't handle META_RESULT_NOT_FOUND,
  causing an assertion failure when deleting non-existent keys
- Most critically, messages sent before TCP connections were established
  were silently dropped with no retry mechanism — added timeout-based
  retry logic in toastyfs_process_events
