🔒 [security fix] Insecure Temporary File Creation in encode.moon

[dsetareh]

🎯 What: The vulnerability fixed was the use of a predictable temporary file path (~/cache_dump.ts) when dumping HLS stream caches.

⚠️ Risk: A predictable filename in a known location can lead to:

1. File Hijacking/Overwrite: Another process or user could create the file beforehand with specific permissions or content.
2. Symlink Attacks: An attacker could create a symbolic link at the predictable path pointing to a sensitive file, causing the script to overwrite it.
3. Collisions: Multiple instances of the script would interfere with each other.

🛡️ Solution:

• Used os.tmpname() to generate unique, non-predictable temporary filenames.
• Added a get_temp_path helper that handles Windows-specific quirks (ensuring absolute paths).
• Introduced a temp_files_to_clean registry and a shutdown event handler to ensure all generated temporary files are deleted, even if the script is interrupted or crashes.
• Properly exported utility functions to maintain compatibility with the project's build process.
