v2.8.4 (versionCode 67)

Patch release - crash-locality precision.

Recent-log timestamps now include milliseconds (HH:mm:ss.SSS); old-format lines are still parsed.
ANR watchdog probes liveness before dumping: after a stall is flagged, a heartbeat is posted and given ~600 ms to run, so dumps distinguish still blocked (live stack captured) from recovered before dump (late report).
ANR files gain a captured_while_blocked field marking capture quality.
Removed stale collaboration statement mentioning an AI assistant name.
