CI Expert and Data Analyst AI agents target development gaps

What this post added

Introduces two new foundational AI agents for the Duo Agent Platform: CI Expert Agent (beta) which automatically generates `.gitlab-ci.yml` configurations based on repository analysis, and Data Analyst Agent (GA) which allows users to query development lifecycle data (MRs, issues, pipelines, jobs) using natural language within Agentic Chat. These agents leverage internal GitLab context for more relevant insights than external tools.
