Changelog

Introduces IConnectionConsumer and ConnectionRequirement types that allow plugins to declare which OAuth providers they require. The shell uses this to conditionally show connection sections in Settings, keeping the UI clean when no plugins need a particular provider.

Add ImportConnectionAsync method to the SDK IConnectionService interface,

allowing plugins to migrate existing refresh tokens to shell-level

connections during the transition from plugin-managed to shell-managed OAuth.

Expand ConnectionsViewModel with Google/Microsoft connection management:

ObservableCollection of OAuthConnectionItem for each provider, connect/disconnect

commands, scope summarization (Gmail, Calendar, Outlook). Add Google and Microsoft

sections to SettingsPanel.axaml with connected accounts list showing email, scope

summary, connected date, and disconnect button per account. Both sections support

multiple accounts with connecting state indicators.

The calendar popup now inherits the width of the trigger button so

the dropdown looks uniform and aligned with the field it belongs to.

The ShowNotes toggle in the graph view now also includes sticky_note

in the allowed node types, so sticky notes appear alongside pages

and wiki sources when the Notes filter is enabled.
