Add Duo User Rules Context support (!195829) · Merge requests · GitLab.org / GitLab

What does this MR do and why?

This is a draft until the cloud connector gets released and updated in this project.

This MR adds another "Duo Context" category. Now you can include open tabs, dependencies, git information, issues, MRs as reference to your Duo (Agentic) Chat.

This MR adds user_rule. This context will contain custom user rules for how the chat should behave.

See the demo in [Agentic Chat] Create custom rules - first iter... (#550743 - closed) to understand the feature.

Issue: #550743 (closed)

Screenshots or screen recordings

The user-facing logic is implemented in the VS Code Extension & Language Server.

How to set up and validate locally

The cloud-connector has not been released yet, so there is a bit of extra effort to make this work.

The full setup end-to-end (not necessary for review) is described here gitlab-org/editor-extensions/gitlab-lsp!1878 (merged)
