Add NetExec, Certipy, Caido, and Censys tools

[fauzan171]

Description

Added 4 new cutting-edge security tools to the toolkit:

Reconnaissance:

1. Caido - A lightweight, modern web security auditing toolkit and proxy. Next-generation alternative to Burp Suite with AI-powered features for web application security testing.
2. Censys Subdomain Finder - Enumerate subdomains using the Censys API. Useful for passive reconnaissance and attack surface discovery.

Lateral Movement:

3. NetExec - The Network Execution Tool, a modern and actively maintained successor to CrackMapExec (which is archived). Enhanced features for network security assessment and post-exploitation with support for SMB, LDAP, MSSQL, SSH, WinRM, FTP, and more.
4. Certipy - Tool for Active Directory Certificate Services (AD CS) enumeration and abuse. Supports certificate theft, privilege escalation, and persistence through AD CS. AD CS attacks are increasingly critical in red team operations.

Why:

• NetExec: CrackMapExec is archived and no longer maintained. NetExec is the community-driven successor with active development.
• Certipy: AD CS attacks have become one of the most important attack vectors in Active Directory environments since the SpecterOps Certified Pre-Owned research.
• Caido: Modern alternative to Burp Suite that is gaining rapid adoption in the security community.
• Censys: Complements existing OSINT tools for comprehensive reconnaissance.
