Tool output truncation now avoids cutting in the middle of a run of identical lines

What

When a large tool-output card is truncated and shown as "N more lines," the logic now scans for consecutive rows that share the same value and only cuts at the boundary between groups, rather than always truncating at a fixed row count as before.

Why

This avoids splitting a block of identical or repeated output lines awkwardly across the truncation point, making truncated tool output easier to read.
