Sub-agent terminal sessions don't inherit proxy environment

[nedalaltiti]

Bug

When the Root Agent creates sub-agents in deep mode, the new tmux terminal sessions don't inherit the Caido proxy configuration (HTTP_PROXY, HTTPS_PROXY, REQUESTS_CA_BUNDLE, SSL_CERT_FILE).

Steps to Reproduce

1. Run Strix in deep mode against an external HTTPS target
2. Root Agent performs recon successfully (curl, katana, nmap work)
3. Root Agent creates sub-agents (e.g., SQLi Discovery Agent)
4. Sub-agent runs curl or httpx → fails with proxy/container errors

Expected Behavior

Sub-agent terminal sessions should inherit the same proxy and CA certificate configuration as the Root Agent.

Root Cause

TerminalSession.initialize() creates a new tmux session with /bin/bash but doesn't source /etc/profile.d/proxy.sh which is where docker-entrypoint.sh writes the proxy vars.

Fix

PR #429 — sources the proxy config in each new terminal session.

Environment

• Strix version: 0.1.13 (sandbox image)
• OS: macOS (Docker Desktop)
• LLM: Gemini 3.1 Pro via Google AI Studio
