[Skill Request] Add security/bug-hunter — Security vulnerability scanner for Android apps

[MartinPSDev]

Summary

I'd like to propose a new skill called bug-hunter, designed to help LLMs perform structured security audits on Android applications, with a focus on bug bounty preparation and OWASP Mobile Top 10 coverage.

I've implemented it in my fork and it's ready for review:

Motivation

Android developers often need to audit their apps before public release, bug bounty submission, or third-party security review. There is currently no security-focused skill in this repository. This skill fills that gap by providing:

• A universal vulnerability checklist covering all major Android attack surfaces (data storage, networking, IPC, cryptography, WebView, binary protections, etc.)
• Vertical-specific checklists for sensitive domains: Banking/Fintech, Health/HIPAA, Enterprise/MDM, and E-commerce
• Context detection logic that automatically identifies the app's domain from package names, dependencies, and manifest entries
• A structured reporting format with severity, OWASP mapping, vulnerable code snippet, and remediation
• A responsible disclosure disclaimer
