On Chromebooks, opening an .eap-config file crashed with an OutOfMemoryError in readBytes (Crashlytics f4def939, 278 events in a week, all on 2.3.1(2693)). Every sampled event failed on the same 128 MB allocation, so the stream held more than 64 MB. The chunked reader from the earlier OOM fix buffered the whole stream with no limit, and Route.buildDeepLink only catches Exception, not OutOfMemoryError.

readBytes now throws FileTooLargeException once the stream passes 10 MB, which buildDeepLink already catches. The user sees the "Not a valid .eap-config file" message instead of a crash. Real profiles are well below 1 MB.

This adds the first unit test source set, with the JUnit alias in the version catalog.

What changed in this PR

Caps .eap-config stream reads at 10 MiB to prevent unbounded buffering and let the existing error handler reject oversized files instead of crashing.

Changes:

• Adds a configurable read limit and FileTooLargeException.
• Adds unit tests for normal reads, size boundaries, endless streams, and stream closure when the limit is exceeded.
• Configures JUnit for the Android app’s first unit tests.
