fix: sanitize subprocess call in main.py

[anupamme]

Summary

Fix critical severity security issue in api/main.py.

Vulnerability

Field	Value
ID	V-001
Severity	CRITICAL
Scanner	multi_agent_ai
Rule	V-001
File	api/main.py:98
Assessment	Likely exploitable

Description: Multiple subprocess calls use user input directly in command execution without proper sanitization, allowing attackers to inject arbitrary shell commands.

Evidence

Exploitation scenario: Attacker provides malicious input containing shell metacharacters (e.g., '; rm -rf /') to parameters passed to subprocess.run() or subprocess.Popen() calls.

Scanner confirmation: multi_agent_ai rule V-001 flagged this pattern.

Production code: This file is in the production codebase, not test-only code.
