Lightdash lineage

Changes

Lightdash reverse lineage

• Trace a Lightdash dashboard or chart back to its dbt models. The Data Explorer panel gains a Lightdash view — open it from the panel sidebar, the DJ: Lightdash — Reverse Lineage command, or a dashboard/chart node in the lineage graph — where you pick an asset, see the mart_* model(s) it depends on, and keep expanding upstream. Each model node can view columns, compile, or run a preview.
• An asset picker built for large projects. Searchable and filterable (All / Dashboards / Charts / Standalone), and responsive across thousands of charts and dashboards. Each entry shows a kind badge and, for charts, the dashboard(s) it belongs to (or Standalone); selecting a chart also shows its parent dashboard(s) in the graph.
• Helpful states. Flags referenced models missing from the project and shows a download banner when no Lightdash content is present. When the dbt manifest isn't parsed, it points you to run dbt parse, then Refresh Projects to re-read it. A toolbar label names the folder it reads from (dj.lightdash.dashboardsAsCodePath); Refresh re-reads that folder to pick up assets you've downloaded or removed.
• More reliable model resolution for Lightdash charts that don't name an explore, fixing both the forward and reverse Lightdash lineage.

Dashboards as Code

• One project per download folder. Downloading a different Lightdash project into a folder that already holds one prompts you to Replace the existing files or Cancel and pick another Save to Path, so a folder's YAML always reflects a single project.
• Visible progress in the post-upload prompt. After an upload, the prompt streams the lightdash download output inline as it refreshes, and offers two clear choices: Refresh from Lightdash (pulls back exactly the charts and dashboards you just uploaded, or the whole project if you uploaded everything) or Close to keep your local files as-is.
