feat(ci): enhance GitHub templates and add configuration files

Phase 2: GitHub Templates & Configuration

Issue Templates:
- Enhanced bug_report.md with Python version and component fields
- Added 'needs discussion' label to feature_request.md for better triage

PR Template:
- Added CI/CD workflow change type
- Expanded checklist with quality gates, documentation, testing, and CI/CD sections
- Added Conventional Commits reminder and branch naming convention
- Better organized sections for code quality, docs, testing

Configuration Files:
- CODEOWNERS: Auto-request review from @alirezarezvani for critical paths
- commit-template.txt: Conventional Commits guide with examples
- dependabot.yml: Weekly Python (pip) and GitHub Actions dependency updates

Aligns templates with new CI/CD workflows from Phase 1:
- PR validation expects Conventional Commits format
- Quality gates check Python, Markdown, Bash, secrets
- Branch naming conventions enforced by pr-into-dev workflow

Next: Phase 3 (dev branch creation, branch protection documentation)
