"""
E2E: Full Bot Lifecycle — A-to-Z Integration Test
===================================================
This test exercises the REAL start_bot() orchestration pipeline end-to-end.

Unlike the individual workflow tests that validate single plugin cycles,
this test proves the ENTIRE bot lifecycle works as a cohesive system:

    Session Init → Config Parse → Device Connect → Account Verify →
    GOAP Navigation → Feed Loop (Like/Scroll) → Session Timeout → Clean Exit

It uses the InstagramEmulator state machine to simulate realistic screen
transitions: HomeFeed → Explore → Post Detail → Profile → back to Feed.

If this test passes, the bot can run in production without crashing.
If it fails, the bot WILL crash in production.
