tk: masterdot shape dedup collapses single-digit count variants (\d+ was \d{2,}) (TK-11965)

shapeOf only normalized 2+-digit numbers, so 'backlog grew 4->7' and
'...grew 11->12' had different shapes and the TK-11676 same-shape dedup never
fired while counts were single-digit early-night. \b\d+\b collapses all count
pairs to one shape. Scoped to the masterdot-agent block; ttys? runs first so
its N is already a letter. No effect on any other creator.
