"""
Basilisk Interactive REPL — manual + AI-assisted red teaming.

Provides a live terminal interface where the user can:
  - Send freeform prompts to the target
  - Run individual attack modules on-demand
  - Trigger evolution on a specific payload
  - View and export findings in real-time
  - Inspect the recon profile
  - Save/load session state
