fix(maintenance): harden extract against directory traversal and absolute path attacks

[ashishsinghbora]

Summary

• Added security inspection of archive member paths prior to extraction to prevent Zip Slip and tar path traversal (../) or absolute path extraction (/etc/...).
• Added checks for missing extractor binaries (tar, unzip, unrar, 7z/7za) with clear error messaging.
• Added -l / --list option to inspect archive contents safely without extraction.
• Added plain .tar format support.
• Fully compatible with --help flag.

Verification

• Tested normal archive extraction on .tar.gz and .zip.
• Tested crafted archives containing ../evil.txt (path traversal) and /evil.txt (absolute path) — verified extraction is strictly blocked and exits non-zero.
• Verified ShellCheck passes without warnings.
• Verified test suite passes.

Code review: confirmed zip slip and tar path traversal checks block malicious ../ and absolute paths, verified tool dependencies are checked before execution, and tested archive extraction.
