Lack of implant sessions in client logs

[hypnoticpattern]

Is your feature request related to a problem? Please describe.
When reading the json_*.log files, it's currently difficult to determine which session/beacon a command was executed in, requiring users to track down the last use ID command.

jq 'select(.level == "DEBUG")' ~/.sliver/logs/clients/op1/json_2025-08-10_18-11-42.log
{
  "time": "2025-08-10T18:11:42.101202985Z",
  "level": "DEBUG",
  "msg": "sessions",
  "type": "command"
}
{
  "time": "2025-08-10T18:11:44.296619485Z",
  "level": "DEBUG",
  "msg": "use 418df39c",
  "type": "command"
}
{
  "time": "2025-08-10T18:11:45.459282175Z",
  "level": "DEBUG",
  "msg": "ls",
  "type": "command"
}
{
  "time": "2025-08-10T18:11:52.00341901Z",
  "level": "DEBUG",
  "msg": "info",
  "type": "command"
}
{
  "time": "2025-08-10T18:11:54.497524988Z",
  "level": "DEBUG",
  "msg": "help",
  "type": "command"
}
{
  "time": "2025-08-10T18:11:59.324111386Z",
  "level": "DEBUG",
  "msg": "background",
  "type": "command"
}
{
  "time": "2025-08-10T18:12:00.270205959Z",
  "level": "DEBUG",
  "msg": "exit",
  "type": "command"
}

Describe the solution you'd like
Add session information when available.

Describe alternatives you've considered
Write a log parser to track the last use of use ID but that is not feasible.
