+/**
+ * Pure tree-building helpers for the Redmine Browser view.
+ *
+ * Algorithmic contract (kept deliberately simple so the UI stays predictable):
+ *
+ *   1. Tickets that are NOT in the input ``tickets`` list (i.e. filtered out
+ *      by the caller) take no part in the relation graph -- they vanish
+ *      completely. No edges, no adjacency entries.
+ *
+ *   2. Roots = tickets whose tracker matches ``rootTrackerId`` (typically
+ *      "Userstory"). Roots are seeded into the BFS queue in ascending id
+ *      order so output is stable across re-renders.
+ *
+ *   3. Construction is a **multi-source breadth-first search**: ALL roots
+ *      are seeded into the queue together. The algorithm then walks
+ *      strictly level-by-level across the entire forest:
+ *
+ *        Level 0: every User Story
+ *        Level 1: every ticket directly related to ANY User Story
+ *        Level 2: every ticket related to a level-1 ticket, ...
+ *
+ *      Consequence: a ticket reachable from two roots ends up under the
+ *      one that finds it FIRST at the shallowest distance. A Feature
+ *      directly related to a User Story is therefore guaranteed to sit
+ *      at depth 1 under that US -- it can never end up nested deeper
+ *      under an Acceptance Criteria just because another root reached
+ *      the AC earlier.
+ *
+ *   4. Each ticket appears AT MOST ONCE in the entire forest (global
+ *      ``visited`` set). Once placed, neither the same nor a different
+ *      relation can pull it elsewhere. Cycles are therefore impossible.
+ *
+ *   5. Tickets that no User Story ever reaches end up under the synthetic
+ *      ``ORPHAN_ROOT_ID``, built with the same multi-source BFS but
+ *      seeded from the orphan candidates.

+// Format string syntax (Excel-inspired, stays simple on purpose):
+//   <ALIGN>:<PATTERN>
+//   ALIGN ∈ { L, M, R }   -- left / middle / right alignment hint
+//   PATTERN may contain literal text wrapped in @...@ (e.g. "@CHF@ #'###.00")
+//
+// Numeric patterns:
+//   - "#'###.00"  Swiss thousands separator + 2 decimals       1'444'555.67
+//   - "0.000"     Force 3 decimals, no thousands separator     4.556
+//   - "0"         Integer, no decimals                         12
+//   - "b"         Auto-scale Byte units (B/KB/MB/GB/TB)        12.3 MB
+//   - "@CHF@ #'###.00" → "CHF 1'234.50"   (literal text via @...@)
+//
+// Binary (boolean) values use ``frontendFormatLabels`` as a 3-tuple
+// [trueLabel, neutralLabel, falseLabel]. ``neutralLabel`` is rendered for
