docs: add CODE_OF_CONDUCT, SECURITY policy, PR/issue templates

[rrahimi-uci]

Goal / Motivation

This repo is public and open to community contributions. GitHub's community health profile flagged several missing files: code of conduct, security policy, PR template, and issue templates.

What changed

• Added CODE_OF_CONDUCT.md (Contributor Covenant 2.1).
• Added SECURITY.md with private vulnerability reporting instructions.
• Added .github/pull_request_template.md.
• Added .github/ISSUE_TEMPLATE/bug_report.md, feature_request.md, and config.yml.

Why this approach

Reuses the same Contributor Covenant text and templates already adopted by this account's higher-scoring repos, for consistency.

Testing

Docs-only change; no code paths affected.

Risks / limitations

None — purely additive documentation/config files.

Docs / config implications

Raises the repo's GitHub community health score; no other config changes.

CODE_OF_CONDUCT.md:25

• The Code of Conduct routes behavioral complaints to GitHub’s private vulnerability reporting, which is intended for security disclosures and can confuse triage and reporters. It’s better to direct CoC reports to a maintainer contact channel (and keep SECURITY.md for vulnerabilities).

Instances of abusive, harassing, or otherwise unacceptable behavior may be reported via GitHub's private vulnerability reporting (**Security → Report a vulnerability**) or by contacting a project maintainer directly through GitHub. All complaints will be reviewed and investigated promptly and fairly.
