NeuroSploit v3.3.0 — Autonomous MD-Agent Engine

Re-model the pentest agent into an autonomous, markdown-driven engine that
turns a URL into a full engagement and delegates execution to a locally
installed agentic CLI backend.

Engine (neurosploit_agent/ + ./neurosploit launcher):
- orchestrator composes ONE master prompt from the agent library + RL weights
- backends: auto-detect & drive Claude Code / Codex / Grok CLI (+ Claude
  subscription); headless, autonomous, isolated workdir
- mcp: Playwright MCP (.mcp.json) for browser-based proof-of-execution
- rl: bounded per-agent reinforcement-learning weights w/ per-tech affinity,
  persisted to data/rl_state.json
- models: latest registry incl. NVIDIA NIM provider (PR #28)
- cli: interactive URL prompt + one-shot `run`, `backends`, `agents`, --dry-run

Agent library (agents_md/, 213 total):
- 196 vuln specialists incl. modern LLM/AI, cloud/K8s, API/auth, advanced
  injection, protocol smuggling, logic/crypto/supply-chain classes
- 17 meta-agents: orchestrator, recon, exploit_validator,
  false_positive_filter, severity_assessor, impact_evaluator, reporter,
  rl_feedback + migrated expert roles
- scripts/build_agents.py data-driven builder; REGISTRY.md index

Docs: rewritten README.md, v3.3.0 RELEASE.md, .env.example (NVIDIA NIM, xAI,
engine vars).

Retire legacy Python orchestration (neurosploit.py + agent classes) to legacy/.

+# HTTP Header Injection Specialist Agent
+## User Prompt
+You are testing **{target}** for HTTP Header Injection.
+**Recon Context:**
+{recon_json}
+**METHODOLOGY:**
+### 1. Host Header Attacks
+- Password reset poisoning: `Host: evil.com` → reset link uses evil.com
+- `X-Forwarded-Host: evil.com` → same effect
+- Cache poisoning: `Host: target.com` + `X-Forwarded-Host: evil.com`
+### 2. X-Forwarded-For Abuse
+- IP-based access control bypass: `X-Forwarded-For: 127.0.0.1`
+- Rate limit bypass: `X-Forwarded-For: random-ip`
+### 3. Other Header Injections
+- `X-Original-URL: /admin` or `X-Rewrite-URL: /admin` (path override)
+- `X-HTTP-Method-Override: DELETE` (method override)
+- `X-Custom-IP-Authorization: 127.0.0.1`
+### 4. Report
+```
+FINDING:
+- Title: Header Injection via [header] at [endpoint]
+- Severity: Medium
+- CWE: CWE-113
+- Endpoint: [URL]
+- Header: [injected header]
+- Effect: [what changed]
+- Impact: Password reset poisoning, access control bypass
+- Remediation: Validate Host header, don't trust X-Forwarded-* blindly
+```
+## System Prompt
+You are an HTTP Header Injection specialist. Header injection is confirmed when a manipulated header changes application behavior — password reset URLs change, access controls are bypassed, or cached content is poisoned. Sending headers without observable effect is not a vulnerability.
