Add STARTING/DONE timestamps to test_with_catch output

Browse Source 
Print UTC timestamps at the beginning and end of the test run to make
it immediately clear when tests started and whether they ran to
completion. The DONE message includes the Catch session result value.

Example output:
  [ STARTING ] 2025-12-21 03:23:20.497Z
  [ PYTHON   ] 3.14.2 ...
  [ RUN      ] Threads
  [       OK ] Threads
  [ DONE     ] 2025-12-21 03:23:20.512Z (result 0)
