The review file tree now renders per-repo top-level nodes when a task's
changes span multiple repositories, so the same file path in two repos
no longer collapses into a single ambiguous entry.
- ReviewFile.repository_id and ReviewFile.repository_name (optional)
identify which repo each file belongs to. Single-repo callers leave
them unset and the tree falls back to the existing flat grouping.
- buildFileTree splits into buildMultiRepoTree (when 2+ distinct
repository_names are present) and buildFlatTree (the original logic).
Repo roots have isRepoRoot=true and a repositoryId for downstream
filters; their children are full path subtrees per repo.
- collapse() skips repo roots so a repo with a single changed file
still shows its repo header.
- ReviewFileTree renders repo roots with a stronger label, a top
border, and an "N files" count badge; data-testid="repo-root-node"
for E2E coverage. File-level rendering is unchanged.
- Tests cover the flat-tree fallback (no repo info, single repo),
multi-repo grouping, repo-root pinning, and same-filename-different-
repos isolation.
