"""Tests for percentage clamping at 100% across display paths.

PR #3480 capped context pressure percentage at 100% in agent/display.py
but missed the same unclamped pattern in 4 other files. When token counts
overshoot the context length (possible during streaming or before
compression fires), users see >100% in /stats, gateway status, and
memory tool output.
