CustomChat 0.1.17

Configuration is grouped by task, with a searchable feature directory. Workspace tools are in the directory rather than a top button grid. Status rows and live preview remain. Provider switches clear stale endpoint overrides; ZIP and YAML import/export guidance is clearer.

Validated: 498 source tests; installed-wheel suite 496 passed, 2 optional skips; browser checks for navigation, provider switches and Nerd import/export.
