annotate task with entry record

[linuxcaffe]

When the hook writes a timeclock entry (on stopping) it should also annotate the task with duration and file-location, something like;
2021-08-18 22:43:05 timelog: (duration: 35m) path/to/my.timeclock
Not just a confirmation that the hook fired properly and the duration has been logged,
but it becomes a two-way link between the records;
The task annotation has the timeclock file, date and time.
The the timeclock entry has all that, and a tag with the task uuid.
