Core events

Event	Payload
`shell/tab.open`	`{ id?, title, viewId, params?, closeEvent?, groupId? }` — opens in the active group by default; a stable `id` restores its saved group after restart. With `closeEvent` the shell emits that event instead of closing the tab itself, so the plugin can confirm unsaved changes
`shell/tab.close` / `shell/tab.activate`	`{ id }`
`shell/tab.update`	`{ id, title?, dirty? }`
`shell/tab.move`	`{ tabId, groupId, index? }` — move or reorder a tab
`shell/tab.split`	`{ tabId, groupId, direction: "left" \| "right" \| "top" \| "bottom" }` — move a tab into a new adjacent group
`shell/panel.toggle`	`{ panel: "left" \| "right" \| "bottom" }`
`shell/status.set`	`{ text }`
`plugins/install.url`	`{ url }`
`plugins/toggle`	`{ id, enabled }`
`plugins/remove`	`{ id }`
`plugins/dependency.missing`	`{ id, toEnable, missing }`
`notes/document.saved`	`{ document }`
`notes/document.save` / `notes/document.saveAs`	`{ docId? }` — save overwrites the known path (desktop) and otherwise opens the picker
`notes/document.close`	`{ docId?, tabId?, force? }` — prompts when the document is dirty unless `force`
`notes/document.saveAndClose` / `notes/document.closeCancel`	answers of the prompt
`i18n/locale.set`	`{ locale }` — change the language
`i18n/locale.changed`	`{ locale }` — emitted after the change
