T8b949e/**

* A bounded in-memory ring buffer of recent Kermit log lines. Desktop has no system logcat, so install this writer at

* startup (`Logger.setLogWriters(platformLogWriter(), InMemoryLogBuffer)`) to let the Debug screen view and export the

* app's own logs. Lines are formatted to loosely match Android's `logcat -v time` shape (`L/tag: message`) so the same

* viewer/filters work on both platforms.
