#  PHOENIX FURY API v4.0 - TITAN CLASS
#
#  - RE-ARCHITECTED: Employs a thread-safe Singleton AttackManager to completely
#    eliminate race conditions and ensure stable, consecutive attacks.
#  - RELIABLE LIFECYCLE: Correctly uses FastAPI's BackgroundTasks for the
#    entire attack lifecycle (start -> wait -> stop), guaranteeing accurate durations.
#  - HTTPS/SSL SUPPORT: L7 worker now intelligently detects secure ports (443)
#    and automatically uses HTTPS, fixing the critical bug of no requests on SSL.
#  - MAXIMUM PERFORMANCE: Retains the high-speed shared memory counter and
#    uvloop event loop for state-of-the-art PPS/RPS throughput.
#  - RESILIENT & ROBUST: Enhanced process cleanup, clearer logging, and a
#    state machine that prevents any overlap between attack runs.
#
#  *** The definitive, stable, and most powerful version. ***
