Extract the inline tree-building logic from IssuesList into a pure `buildIssueTree` function in lib/issue-tree.ts so it can be unit tested. Add six tests covering: flat lists, parent-child grouping, multi-level nesting, orphaned sub-tasks promoted to root, empty input, and list order preservation. Add two tests to IssueRow.test.tsx covering the new titleSuffix prop: renders inline after the title when provided, and renders cleanly when omitted. Co-Authored-By: Paperclip <noreply@paperclip.ing>
