Implementation of merge_user_events(events) with sessioning, deep meta merge, and ordered type counts.

Local run:

python3 test_main.py

Docker:

docker build -t rayka-challenge .
docker run --rm rayka-challenge

Docker Compose:

docker compose up --build --abort-on-container-exit

• Events are grouped per user_id and split into sessions when adjacent events are more than 600 seconds apart.
• types uses first-seen order with counts to preserve frequency while removing duplicates.
• meta is deep-merged with earliest non-dict values winning conflicts.

• main.py implementation
• test_main.py minimal tests
• Dockerfile, docker-compose.yml, requirements.txt
