Add gitl to DevOps Tools

[akomyagin]

Adds gitl (git-log-lens) — a Go CLI tool + GitHub Action for AI-powered code review of git commit ranges with structured risk scoring.

Commands:

• gitl review <range> — AI review with low/medium/high risk score, CI gating via --fail-on
• gitl changelog — Keep a Changelog-style output from conventional commits
• gitl digest — activity summary across multiple repos in parallel

Features:

• BYOK: OpenAI-compatible API, Ollama (local), Azure OpenAI
• Works offline without an API key (deterministic heuristic fallback)
• GitHub Action posts sticky PR comment with risk score
• Binaries signed with cosign keyless (Sigstore)
