fix(windows): stabilize local and SSH execution for wizard and sessions

- Use full agent path (claude.exe) on Windows to avoid shell:true
  which breaks stdin piping for stream-json input mode
- Fix SSH condition to check enabled flag, not just config existence
- Pass sessionSshRemoteConfig through inline wizard to enable remote execution
- Add synopsis SSH inheritance from parent session as backend workaround

Fixes local wizard crashing with exit code 1 and SSH sessions
incorrectly using local paths when SSH was disabled.

+# Building and Running on Windows
+
+This guide provides instructions for setting up your environment and running the Maestro application on a Windows machine.
+
+## Prerequisites
+
+Before you begin, ensure you have the following installed:
+
+*   **Node.js:** Version 22 or later.
+*   **Python:** Version 3 or later.
+
+Additionally, you will need the Visual Studio Build Tools to compile native Node.js modules used in this project.
+
+### Installing Visual Studio Build Tools
+
+1.  **Download the Build Tools:**
+    *   Go to the [Visual Studio Downloads page](https://my.visualstudio.com/Downloads?q=Visual%20Studio%202022).
+    *   You may need to log in with a Microsoft account.
+    *   Download the **Build Tools for Visual Studio 2022**.
+
+2.  **Run the Installer:**
+    *   When the installer launches, you will be prompted to select workloads.
+    *   Check the box for **Desktop development with C++**.
+    *   Proceed with the installation.
+
+3.  **Verify the Setup:**
+    *   After the installation is complete, open a PowerShell terminal in the project root.
+    *   Run `npm ci` to install dependencies. If you have already run `npm install`, you can run `npx electron-rebuild` to rebuild the native modules.
+
+## Running the Application in Development Mode
+
+There are two ways to run the application in development mode on Windows: using the provided script or by running the steps manually.
+
+### Using the Development Script (Recommended)
+
+The easiest way to start the development environment is to use the `dev:win` npm script. This script automates the entire process.
+
+Open a PowerShell terminal and run:
+```powershell
+npm run dev:win
+```
+
+This will handle all the necessary build steps and launch the application.
+
+### Manual Steps
+
+If you encounter issues with the `dev:win` script or prefer to run the steps manually, follow this procedure.
+
+1.  **Build the application:**
+    ```powershell
+    npm run build
+    ```
+
+2.  **Start the Vite renderer:**
+    ```powershell
+    npm run dev:renderer
+    ```
+
+3.  **Start the Electron main process:**
+    Open a **new** PowerShell terminal and run the following command:
+    ```powershell
+    npm run build:prompts; npx tsc -p tsconfig.main.json; $env:NODE_ENV='development'; npx electron .
+    ```
+
+This will launch the application in development mode with hot-reloading for the renderer.
