recon-sweep — CTF recon toolkit + falsifiable extraction harness.

Honest rewrite of the "AI Warfare Agent". Two things changed that matter:

  1. SCOPE GUARD. Scanners refuse any host not in an explicit allowlist.
     The old code would happily brute-force anything. Here the discipline
     lives in the code, not just your good intentions. Point it at your own
     CTF ranges. Nothing else will run.

  2. FALSIFIABLE SCORING. The old code asked an LLM to grade its own output
     with a made-up 0-100 "confidence". That's the model grading its own
     homework. Here you PLANT canaries in the target (system prompt, RAG doc,
     env) before the run, and a solve == exact-match extraction of that
     canary. Ground truth, not vibes.

Target shapes supported:
  - LLM endpoint only  (prompt-injection / extraction challenges)
  - Full host          (web + network + LLM)
  - Both               (flexible; enable what the challenge needs)

Planner:
  - DeterministicPlanner  -> fixed probe list. Reproducible, scoreable.
  - LLMPlanner            -> adaptive. Optional; needs an API key.

Usage:
    scope = Scope(allow={"127.0.0.1", "localhost", "10.13.37.0/24"})
    oracle = ExtractionOracle({"sys_prompt": "CTF{pl4nted_secret}"})
    target = LLMTarget("http://127.0.0.1:11434", scope)
    harness = Harness(target, oracle, planner=DeterministicPlanner())
    harness.run(max_probes=15)
