Append a line (vector of fragments) to a uiMessageLog entity.
Queues a buffered mutation that swaps lines for a fresh array (FIFO-truncated to
maxLines) — the array-identity change is the sync system's redraw signal — and
synchronously publishes uiLogAppended carrying the line for entry-animation
listeners. Safe to call from inside a system process callback.
