NeuroSploit v3.3.0 — minimalist web GUI server (stdlib only).

A tiny, dependency-free web front-end for the autonomous engine. Tabs:
  * Run       — URL, backend/model, collaborator, verbosity, RL + MCP toggles
  * Agents    — browse the 213-agent library; add new .md agents from the UI
  * Insights  — interactive chart of agent outputs (findings + RL weights)
  * Settings  — API keys per provider, execution mode (CLI backend vs API),
                main orchestrator agent

    python3 webgui/server.py            # serves http://127.0.0.1:8787

No npm, no build step, no FastAPI. It talks to neurosploit_agent directly.
