First flush any buffered telemetry to the portal, then display usage stats.

Run the following shell command and display the output to the user exactly as returned:

```bash
cielara telemetry-flush --once >/dev/null 2>&1 || true; cielara stats
```

`cielara telemetry-flush --once` pushes locally-buffered usage events
(`~/.cielara/telemetry.ndjson`) to the portal before reading stats — failures are
non-fatal, stats are still shown. Use the global `cielara` binary on PATH, not
`node bin/cielara.js` (cwd-relative, breaks from other directories). Do not add
commentary. Just show the stats output.
