Joey Yakimowich-Payne d44b433889 feat(chess/ui): add narrate.ts pure module for descriptor → English Pure tree-walker that converts CustomModifierDescriptor (or just an EffectPrimitiveNode array) to a human-readable English narrative. - Static KIND_NARRATORS map covers all 21 primitives (14 existing + 7 T1-extension trigger kinds: on-move, on-turn-end, on-promotion, on-check-received, on-check-delivered, on-moved-onto-square, on-captured) — no PRIMITIVE_REGISTRY lookup so the module stays free of engine/Session/Rete imports. - Cycle guard via WeakSet on node identity outputs '…' on revisit; length cap 4000 chars truncates with ' … and N more primitives'. - Performance: 0.091ms avg on 50-node descriptor (11x under the 1ms budget for live preview). - 34 tests cover every kind, nested combinations, cycle handling, truncation, and perf microbenchmark. Used by the live-preview pane (T17) added later in this epic.		2026-04-21 16:57:10 -06:00
