Changelog

Merges the shell's intent suggestion tray and plugin-local AI panels into a

single global "AI Suggestions" tray owned by the desktop shell.

New files:

• AiSuggestionServiceImpl: wraps WeakReferenceMessenger for Push/Update/Remove
• AiSuggestionTrayViewModel: subscribes to IntentEngine events + content

suggestion messages, aggregates both card types into one ObservableCollection

• ContentSuggestionCardViewModel: wraps ContentSuggestionCard, sends

ActionRequested/Dismissed messages back to owning plugin

• IAiTrayCardViewModel: common interface for Intent and Content card VMs
• AiSuggestionTray.axaml: DataTemplate-based rendering for both card types

Removed:

• IntentSuggestionTrayViewModel (replaced by AiSuggestionTrayViewModel)
• IntentSuggestionTray.axaml (replaced by AiSuggestionTray.axaml)

Renamed in MainWindowViewModel:

• IntentTrayVM → AiTrayVM, IsIntentTrayOpen → IsAiTrayOpen
• ToggleIntentTray → ToggleAiTray

Updated MainWindow.axaml bindings, Keyboard.cs escape handler, PluginHost/

PluginHostFactory wiring, and ServiceRegistration DI container.

Desktop version 1.48.3 → 1.49.0.

Introduces the SDK contract for the global AI suggestion tray:

• ContentSuggestionCard, SuggestionAction, ContentSuggestionState models
• Messenger messages: Push/Update/Remove/ActionRequested/Dismissed
• IAiSuggestionService interface (Push, Update, Remove)
• IPluginHost.Suggestions property for plugin access
• SDK version bump 1.48.0 → 1.49.0

Plugins can now push content suggestion cards (summaries, rewrites, etc.)

into a shell-owned unified tray via Host.Suggestions. Action clicks route

back to the owning plugin via ContentSuggestionActionRequestedMessage on

the messenger bus, keeping block-level operations inside the plugin while

the shell renders cards uniformly alongside intent suggestion cards.

Implements the new IDataObjectProvider.AggregateGroupedAsync method,

delegating to the underlying IDatasetService for multi-series grouped

aggregate queries. Bumps Data plugin version from 1.17.0 to 1.18.0.

New "Generate Insights" button in the dataset browse header. Clicking it

queries the first 100 rows, pushes a Loading suggestion card to the AI tray,

and sends DatasetInsightRequestMessage to the shell orchestrator for AI

analysis. The orchestrator handles the AI call and note creation.

New partial class DatasetBrowseViewModel.Insights.cs keeps insight logic

separate. IAiSuggestionService wired through DataPlugin → DataViewModel →

DatasetBrowseViewModel.

Fixes global keyboard shortcuts (Cmd+K, Cmd+/, Cmd+\, etc.) not firing when

focus is inside TextBox or RichTextEditor controls. The root cause was that

MainWindow.OnKeyDown() used bubble-phase routing, so text controls consumed

KeyDown events before they reached the window. Switched to tunnel-phase

routing via AddHandler(KeyDownEvent, handler, RoutingStrategies.Tunnel),

matching the pattern already used by NavigationSidebar.

Split MainWindow.axaml.cs (593 lines) into three partial classes for

modularity: MainWindow.axaml.cs (lifecycle + pointer handlers),

MainWindow.Keyboard.cs (all global shortcut handling),

MainWindow.Speech.cs (speech-to-text helpers).

Added QuickActionService that aggregates IQuickActionProvider capabilities

from plugins and surfaces them as command palette entries. Wired quick action

overlay in MainWindow.axaml with modal backdrop, title bar, and dynamic

ContentPresenter. Added overlay state properties to MainWindowViewModel.

Registered IQuickActionProvider auto-discovery in PluginRegistry.ActivatePlugin

and QuickActionService as a command provider in SetMainViewModel.
