fix(process): add missing processHandle/currentPID helpers + trim daemon payload

- process_handle.go: new file adding processHandle(pid) wrapping os.FindProcess
  and currentPID() wrapping os.Getpid — referenced by pidfile.go but never
  defined, breaking the build on dev
- pkg/api/provider.go: drop daemonEventPayload entries for entry.Config and
  entry.StartedAt — fields don't exist on DaemonEntry (which has Started time.Time)

Unblocks go-process dev build + tests (10s root, 0.9s exec, 7s api).
