fix(security): remediate Zip Slip vulnerability and update dependency…

[rakesh-talanki]

… overrides

• Add strict directory boundary validation in unzipProxy (lib/deploycommon.js) to prevent Zip Slip directory traversal (CWE-22)
• Add automated unit test in test/testzip.js to verify Zip Slip prevention
• Upgrade tar-fs to ^2.1.4 to fix symlink validation bypass and path traversal
• Move body-parser from dependencies to devDependencies to reduce production bundle attack surface
• Replace lodash.find with native Array.prototype.find in testzip.js
• Configure npm overrides for path-to-regexp, brace-expansion, serialize-javascript, picomatch, minimatch, js-yaml, qs, cookie, diff, ajv, uuid, and node-emoji
• Result: 0 npm audit vulnerabilities (down from 17); all 92 specs pass
