Connect your agents to your software lifecycle with the GitLab MCP server

Introduces the GitLab MCP server, now generally available, which acts as an open standard for agents to interact with GitLab workflows. It provides a curated set of tools for agents to access code, pipelines, and group/wiki information with fewer API calls and reduced context bloat. New tools include `add_branch`, `get_repository_file`, `semantic_search`, `get_pipeline`, `list_pipelines`, `get_artifact_file`, `list_groups`, and `list_wiki_pages`. It also details how agents can initiate GitLab Duo Agent Platform flows directly from their client tools using new commands like `list_duo_agents_and_flows`, `start_duo_session`, `get_duo_session`, and `list_duo_sessions`. Toolsets are introduced to allow agents to work with a focused set of tools.
