Files Index

Slim per-file rows for the browsable Files index + treemap.

One row per indexed file node, joined in-memory from the artifacts the indexer already uploads (graph nodes, graph metrics, health metrics, git metadata). Importance (pagerank) percentiles are computed once over the full set — before any limit/offset slice, whose window is applied last (totals always reflects the full pre-slice set). Returns state='not_available' when the snapshot has no graph artifact (pre-graph index) so the page renders an honest empty state.
