Show output logs for a specific CocoFleet instance. If the instance is still running, tails the live log. If complete, shows the full log with status summary. Usage: $fleet logs [fleet-id] [instance-id].

Your objective is to show output logs for a CocoFleet instance.
Before proceeding, verify that `.cocoplus/` exists.
If not: output "CocoPlus not initialized in this directory. Run `$pod init` to begin." Then stop.
Parse arguments: `$fleet logs [fleet-id] [instance-id]`
If missing: output "Usage: $fleet logs [fleet-id] [instance-id]" Then stop.
Log file: `.cocoplus/fleet/[instance-id]/output.log`
If not found: output "No log file found for [instance-id]. The instance may not have started yet." Then stop.
Read state file to determine if instance is still running.
Check if PID in state.json is alive using a cross-platform Node.js one-liner:
`node -e "try{process.kill([pid],0);console.log('alive')}catch(e){console.log('dead')}"`
If alive (instance still running):
- Output last 50 lines of output.log
- Append: "[Instance is still running — showing last 50 lines. Re-run `$fleet logs` to refresh.]"
If dead (instance complete or stopped):
- Output full log content
- Append status summary from state.json (completed/failed, checkpoints satisfied)
## Anti-Rationalization
| Shortcut / Temptation | Why It Fails |
|-----------------------|--------------|
| Always show full log regardless of whether instance is running | For running instances, full log output may be many thousands of lines — tail 50 is the correct live view |
| Show logs without checking instance status first | Showing "complete" status for a still-running instance misleads the developer into thinking work is done |
## Exit Criteria
- [ ] Log content from `.cocoplus/fleet/[instance-id]/output.log` is displayed
- [ ] If instance is running: only last 50 lines shown with a "[still running]" notice
- [ ] If instance is complete: full log shown with status summary from state.json (checkpoints satisfied or not)
