[Bug] PowerSearch: the clear-all button removes only the last filter per press

[nowgnuesLee]

Description

PowerSearch's clear-all button doesn't clear all filters. Each press removes only the last one. Expected: one press removes every filter.

Reproduction

Reproducible on the public Storybook: Core/PowerSearch › Pre-set Filters

1. Open the story. Two filters are applied, one on Status and one on Priority.
2. Click the clear-all button ("Clear all", at the right edge of the input).
3. Actual: only the "Priority" token is removed. A second press removes the remaining one.
4. Expected: both tokens are removed in one press.

With more filters the effect is easier to see: Core/PowerSearch › Many Filters needs one press per filter.

Astryx Version

@astryxdesign/core@0.5.4. The same code path is unchanged in 0.6.2 and on main @ 65c6718.

Environment

Not environment-specific; this is state logic in PowerSearch. Reproduced on the public Storybook.
