Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request ensures that the application state remains consistent when a user switches workspaces. By introducing an IPC event to signal workspace changes and adding cleanup logic to all primary data stores, the renderer can now effectively clear stale data and re-initialize from the new workspace database without requiring a manual application restart.

Code Review
This pull request implements a mechanism to refresh and re-hydrate renderer stores when switching workspaces, introducing a workspace:changed IPC broadcast from the main process and corresponding reset methods across several stores. The review feedback highlights critical concurrency and data integrity concerns: a race condition in refreshWorkspaceData could allow in-flight syncs from a previous workspace to pollute the new database, and active sync chains should be cleared during hydration reset. Additionally, a defensive check is recommended to prevent errors when broadcasting to destroyed windows.
Important

Critical: Race Condition and Potential Cross-Workspace Data Pollution
When switching workspaces, refreshWorkspaceData triggers asynchronous operations (hydrateFromLocal and syncFromGateway). If a user switches workspaces rapidly, or if there are overlapping refresh events, multiple instances of these asynchronous operations can run concurrently.
More importantly, if an in-flight syncFromGateway or hydrateFromLocal from the previous workspace is still running when the database is switched, it may resolve and write/persist data belonging to the old workspace into the new workspace's database (since the global database connection in the main process has already been pointed to the new workspace). This violates workspace isolation and the Message Integrity invariant.
We should implement a concurrency guard (using a session/generation ID) to ensure that only the latest workspace refresh is allowed to complete and perform side effects.

High: Clear Active Sync Chains on Workspace Reset
When resetting the hydration state for a workspace change, any active sync chains in syncChains should be cleared. Otherwise, queued sync operations for the old workspace's session keys might still execute and attempt to write to the newly opened database, leading to potential data pollution or duplicate messages.
resetHydration: () => {
hydrationPromise = null;
syncChains.clear();

Medium: Defensive Check for Destroyed Windows
When broadcasting the workspace change event, BrowserWindow.getAllWindows() can return windows that are in the process of being closed or already destroyed. Calling win.webContents.send on a destroyed window can throw an error and potentially crash the main process or cause unhandled promise rejections.
It is safer to check if the window and its webContents are active and not destroyed before sending the IPC message.
function broadcastWorkspaceChanged(workspacePath: string): void {
for (const win of BrowserWindow.getAllWindows()) {
if (!win.isDestroyed() && win.webContents && !win.webContents.isDestroyed()) {
win.webContents.send('workspace:changed', { workspacePath });
}
}
