Adds lifecycle logger to log start, complete, and failure logs

[micahwoodard]

Describe changes:

Adds lifecycle logger to log start, complete, and failure logs using the aind-log-utils formatter. This will create a log file in a default folder of Documents/lifecycle_logs to be picked up by grafana alloy. Start log will emit after user presses start and acquisition name is defined and stop log will happen after user saves. Final logs will look like

{"timestamp": "2026-05-27T15:02:30.306808Z", "level": "INFO", "message": "Session started.", "subject_id": "0", "acquisition_name": "behavior_0_2026-05-27_08-02-30", "event_type": "stage_start"}
{"timestamp": "2026-05-27T15:03:02.180110Z", "level": "INFO", "message": "Session ended.", "subject_id": "0", "acquisition_name": "behavior_0_2026-05-27_08-02-30", "event_type": "stage_complete"}

What issues or discussions does this update address?

Describe the expected change in behavior from the perspective of the experimenter

• None

Describe any manual update steps for task computers

• Need to set up grafana alloy on the frg computers to pick up logs. This can be done asynchronously.

Was this update tested in 446/447?

• 446/7

Does this update impact downstream processing by adding new saved files, or changing their format? If so, have you documented changes?

• does not impact data but log will be used for session tracking. Coordinating with SciComp

Nice! It's great to see the log-schema dependency added
