pytest configuration for integration tests.

These tests require external tools (QEMU binary, arduino-cli, ESP-IDF toolchain)
and are NOT run in standard CI.  Run them manually:

    pytest test/backend/integration/ -v

or target a single file:

    pytest test/backend/integration/test_compilation.py -v
