This PR introduces a standard SECURITY.md policy file to the repository.
While reviewing the codebase, I noticed there wasn't a defined channel for the private, responsible disclosure of security vulnerabilities. Adding this policy helps protect the project by guiding researchers to report bugs privately rather than in public issues.
I highly recommend merging this and enabling GitHub's "Private Vulnerability Reporting" feature in your repository settings. I currently have some security findings I would like to share with the maintainers securely once a private channel or contact method is established.
