Enhance Security Documentation and Vulnerability Management Processes

## Labels
`documentation` `security` `process` `good first issue`

## Description

### Background
Strong security isn't just about code—it's about people, processes, and documentation. As our platform grows and attracts more contributors, we need comprehensive security documentation and formalized processes to maintain our security posture at scale.

### Problem Statement
Currently, our security practices have several gaps:
- **Limited Documentation**: Security architecture and threat models aren't well documented
- **Ad-hoc Processes**: Vulnerability handling is reactive rather than proactive
- **Knowledge Silos**: Security knowledge concentrated in a few team members
- **Unclear Guidelines**: Contributors lack clear security coding standards
- **No Training Program**: No formal security onboarding or ongoing training

### Proposed Solution
Establish comprehensive security documentation and formalize vulnerability management processes to create a mature, scalable security program.
