## Summary by cubic
Let users pick where each app is stored and move apps safely. Adds a
simple “Change location” flow, supports absolute paths, and shows each
app’s resolved path.

- **New Features**
- Paths: getDyadAppPath accepts absolute paths; apps include
resolvedPath; removed global appBasePath from list-apps and state.
- UI: App Details shows full path with “Show in folder” and a “Change
location” dialog. We stop the app, copy without node_modules, check
conflicts, and update DB to an absolute path.
- IPC: Added select-app-location and change-app-location. Rename blocks
absolute paths; copy/rename exclude node_modules; conflict checks use
resolved paths.
  - Tests: Added e2e test for moving an app to a custom folder.

> [!NOTE]
> Introduces per-app folder relocation with safety checks and exposes
each app’s resolved path for clarity.
> 
> - **IPC/Backend**: Adds `select-app-location` and
`change-app-location` to move app folders (stop app, validate absolute
destination, conflict checks via `getDyadAppPath`, copy without
`node_modules`, cleanup/rollback, store absolute `path`).
`list-apps`/`get-app` now include `resolvedPath`. `getDyadAppPath`
accepts absolute paths. `rename-app` forbids absolute targets, preserves
dir for existing absolute paths, adds robust conflict checks and
cleanup; copy/rename exclude `node_modules`.
> - **UI**: App Details shows `resolvedPath`, adds "Move folder" dialog
and "Show in folder" action; removes reliance on `appBasePath`.
> - **Client/Preload**: `IpcClient` methods for new handlers; preload
whitelists new channels.
> - **Tests**: New e2e covers moving an app and verifying path update.
