Fixes a regression introduced in 629df07 where adb devices -l output containing non-key-value attributes (e.g. ABCDEFG device 20-30 product:mokey model:mokey device:mokey transport_id:1) caused regex lazy-matching to backtrack, incorrectly capturing ABCDEFG device into Group 1 (the device ID).

This change:

  • Updates _kDeviceRegex in android_device_discovery.dart to explicitly match known ADB device states (device, offline, unauthorized, no permissions, etc.) and require a column delimiter of at least two spaces or a tab ((?:\s{2,}|\t+)).
  • Adds regression unit test coverage in android_device_discovery_test.dart.

Related to #189274

Tests

  • Added regression unit test in android_device_discovery_test.dart for ADB output containing non-key-value attributes.
  • Added unit test for wireless serial names containing spaces and state keywords (my device (2)).

Fixes a regression introduced in 629df07
where `adb devices -l` output containing non-key-value attributes (e.g.
`ABCDEFG           device 20-30 product:mokey model:mokey device:mokey transport_id:1`)
caused regex lazy-matching to backtrack, incorrectly capturing `ABCDEFG           device`
into Group 1 (the device ID).

This change:
* Updates `_kDeviceRegex` in `android_device_discovery.dart` to explicitly match
  known ADB device states (`device`, `offline`, `unauthorized`, `no permissions`, etc.)
  and require a column delimiter of at least two spaces or a tab (`(?:\s{2,}|\t+)`).
* Adds regression unit test coverage in `android_device_discovery_test.dart`.

Code Review

This pull request updates the regular expression used to parse adb devices output in AndroidDevices to prevent false positives by requiring a wider column separator and explicitly listing known ADB device states. It also adds corresponding unit tests to verify parsing behavior with extra attributes and serials containing spaces. The review feedback suggests adding the rescue state to the list of explicit ADB device states to support modern Android/ADB versions.
