[HIGH] Create ISSUE_TEMPLATE.md and PULL_REQUEST_TEMPLATE.md

[kilodesodiq-arch]

Engineering Gap

No .github/ISSUE_TEMPLATE.md or .github/PULL_REQUEST_TEMPLATE.md. Community contributions lack structure and required information fields.

Codebase Evidence

• .github/ directory contains only workflows/ subdirectory
• No issue template, PR template, or config.yml
• README.md CONTRIBUTING section exists but no template enforcement

Risk Profile

Current Risk

Inconsistent bug reports missing reproduction steps. PRs without test plans or description. Reviewer time wasted on incomplete submissions.

Business Impact

Higher contribution review overhead. Lower quality community contributions. Slower development velocity.

Remediation Strategy

Create ISSUE_TEMPLATE.md with bug report and feature request sections. Create PULL_REQUEST_TEMPLATE.md with description, testing, and checklist sections.

Success Conditions

• ISSUE_TEMPLATE.md created in .github/
• PULL_REQUEST_TEMPLATE.md created in .github/
• Issue template includes: description, reproduction, expected behavior, environment
• PR template includes: summary, testing, screenshots, checklist

Change Surface

New files: .github/ISSUE_TEMPLATE.md, .github/PULL_REQUEST_TEMPLATE.md

Security Review

No security impact.
