* Dumps this app's own logcat, filtered to our process id via `--pid` (API 24+, minSdk is 26). Without READ_LOGS the OS

* already limits us to our own entries, but `--pid` guarantees it even if that permission is ever granted (e.g. via adb

* on an emulator) so a shared bug report can't leak other apps' logs. Best-effort: a capture failure returns a marker

* rather than throwing. ProcessBuilder with a merged stderr avoids a pipe-buffer deadlock, and the bounded wait keeps a

* stuck capture from tying up the IO thread.
