Why?

PlanetScale's throttler ratio uses brake semantics: 0 means "no braking" (full speed), 100 means "fully braked" (paused). This is counter-intuitive — a ratio of 0 looks like "zero work" or "fully paused" when read without context. An LLM consuming this tool's output misinterpreted ratio: 0 as "deployment is frozen" when it was actually running at maximum speed.

How?

Adds a ratio_description field alongside each numeric ratio value in the throttler configurations response, and updates the tool description to explain the brake model.

The PlanetScale throttler ratio is a brake (0 = full speed, 100 = paused),
which is counter-intuitive. An LLM misread `ratio: 0` as "fully paused"
during a production deploy request audit. Adding `ratio_description` to the
response ensures the semantics are visible at interpretation time, not just
in the tool schema.
