Android logs

The human command returns a finite snapshot for the running application selected by package PID:

cargo ferry logs android --device SERIAL
cargo ferry logs android --device SERIAL --since-seconds 60 --level warning

Bounds default to a five-minute window, 2,000 retained entries, and 2 MiB. Override them with --since-seconds, --max-entries, and --max-bytes. RustFerry uses adb logcat --pid and never clears the global log buffer. The application must already be running.

For continuous protocol output, add --json-stream:

cargo ferry logs android --device SERIAL --json-stream

Each application-filtered entry is emitted as a bounded protocol event until Ctrl+C or platform-tool exit. Cancellation terminates the process tree. There is no automatic reconnect after process restart, disconnect, or adb logcat exit.

The VS Code Open Logs command consumes this structured live stream; Stop Logs cancels it. No Android target was available in the current validation environment, so live device output was not observed.
