Add millisecond-granularity delay_task_ms() to delaymgr using clock_gettime(CLOCK_MONOTONIC) for deadline computation. Extends delay_task_t with nextrun_ts field; delay_worker distinguishes ms-tasks from second-tasks via non-zero nextrun_ts. Backward compatible with existing delay_task callers. 4 delay tests pass (2 new: tolerance and invalid-args). Provides the timeout primitive for election and committing watchdogs.
