- Split the one-shot keep-open intent from the in-flight guard and consume it before the
first await, so a Save clicked while an Apply is in flight closes the modal.
- Refresh the dependent groups only when the settings PUT returned ok (_apiPut answers null
or a non-ok response instead of throwing), and also when only the webhook save failed.
- Find the 'Apply or Save' hint by a data marker, not its English text; add zh-CN strings
for the new toast and title.
- Tests run the real saveAppSettings() (Apply then Save mid-flight, a failed PUT, a webhook-only
failure, a plain Save).
- Narrow the changeset and JSDoc to MCP sync and CLI management; touch the tray comment, the
architecture note and the wiki.
