Add cleanup trap to smoke-init.sh that kills all mock-forgejo.py processes
on exit (success or failure). Also ensure cleanup at test start removes
any leftover processes from prior runs.
In .woodpecker/smoke-init.yml:
- Store the PID of the mock-forgejo.py background process
- Kill the process after smoke test completes
This prevents accumulation of orphaned Python processes that caused
OOM issues (2881 processes consuming 7.45GB RAM).
