fix(websearch): update existing hook config when filename changes

Previously, ensureHookConfig() would return early if any WebSearch hook
existed in settings.json, even if it pointed to an old/renamed file.
Now it checks if the command path matches the expected hook and updates
it if needed.

This fixes the "No Providers Configured" error when the hook file was
renamed from websearch-gemini-transformer.cjs to websearch-transformer.cjs.
