fix: use subprocess instead of os.system in franceinfo.py

[anupamme]

Summary

Fix high severity security issue in Streams/Python/franceinfo.py.

Vulnerability

Field	Value
ID	V-001
Severity	HIGH
Scanner	multi_agent_ai
Rule	V-001
File	Streams/Python/franceinfo.py:54
Assessment	Likely exploitable

Description: The Python scripts use os.system() to execute shell commands for file deletion with hardcoded strings. The wildcard 'rm watch*' could delete unintended files if the working directory changes or if an attacker creates files matching the pattern. Using os.system() for file operations is a security anti-pattern that can lead to unintended consequences.

Evidence

Exploitation scenario: An attacker with write access to the script's execution directory could create files named 'watch_important_config' or similar that match the 'watch*' pattern.

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

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