Refactor(docs): Relocate developer and prerelease installation guides

- Moves "Local Setup & Development" instructions from the main installation guide to a new dedicated page: `docs/advanced-usage/local-development-setup.mdx`.
- Creates a new page for "Prerelease Build" information (covering Roo Code Nightly) at `docs/advanced-usage/prerelease-build.mdx`.
- Updates `docs/getting-started/installing.mdx` to remove the detailed sections and instead link to these new, more appropriately placed advanced usage guides.
- Adjusts `sidebars.ts` to correctly list the new pages under the "Advanced Usage" category.
- Adds new image `static/img/installing/installing-5.png` for the prerelease build documentation.

This restructuring improves the organization of the installation documentation by separating standard installation procedures from more advanced topics like local development and using prerelease software.

+## Local Setup & Development
+
+:::note Developer Information Only
+This section is for developers contributing to Roo Code or those who wish to build and run the extension from source.
+:::
+
+To set up Roo Code for local development:
+
+1.  **Clone the repository:**
+    ```bash
+    git clone https://github.com/RooCodeInc/Roo-Code.git
+    cd Roo-Code
+    ```
+
+2.  **Install dependencies:**
+    Roo Code uses `pnpm` for package management.
+    ```bash
+    pnpm install
+    ```
+
+3.  **Run the extension for development:**
+    You have two primary methods:
+
+    *   **Directly in VS Code (Recommended for active development):**
+        *   Open the cloned `Roo-Code` folder in VS Code.
+        *   Press `F5` (or select **Run** → **Start Debugging** from the menu). This opens a new VS Code window (Extension Development Host) with Roo Code running.
+        *   Changes to the webview code (under `webview-ui/`) will often update live.
+        *   Changes to the core extension code (under `src/`) typically require restarting the Extension Development Host window.
+
+    *   **Building and Installing a VSIX package:**
+        This method is useful for testing the packaged extension or distributing development builds.
+        1.  Build the VSIX file:
+            ```bash
+            pnpm build
+            ```
+            A `.vsix` file (e.g., `roo-cline-<version>.vsix`) will be created in the `bin/` directory.
+
+        2.  Install the VSIX in VS Code:
+            *   **Using the command line:**
+                ```bash
+                code --install-extension bin/roo-cline-<version>.vsix
+                ```
+                (Replace `<version>` with the actual version number in the filename).
+            *   **Using the VS Code interface:**
+                *   Open the Extensions view (`Ctrl+Shift+X` or `Cmd+Shift+X`).
+                *   Click the "..." (More Actions) menu in the Extensions view sidebar.
+                *   Select "Install from VSIX..."
+                *   Browse to and select the generated `.vsix` file from the `bin/` directory.

+# Prerelease Build
+
+For users who want the latest features and updates, Roo Code offers prerelease builds. The primary prerelease build is **Roo Code Nightly**, which is automatically published whenever changes are merged into our main development branch.
+
+**Note:** As prerelease software, these builds may occasionally include experimental features or bugs. They are best suited for users comfortable with testing cutting-edge software.
+
+To install a prerelease build like Roo Code Nightly:
+
+1.  Open VS Code.
+2.  Access Extensions: Click the Extensions icon in the Activity Bar or press `Ctrl+Shift+X` (Windows/Linux) or `Cmd+Shift+X` (macOS).
+3.  Search for "Roo Code Nightly" (or the specific prerelease build name).
+4.  Select the prerelease extension (e.g., "Roo Code Nightly" by RooVeterinaryInc) and click **Install**.
+    *   If you have the stable version of Roo Code installed, the Marketplace might show an option to "Switch to Pre-Release Version" for the Roo Code extension itself, or you might find "Roo Code Nightly" as a separate listing.
+5.  Reload VS Code if prompted.

+*Roo Code Nightly (prerelease build) in the VS Code Marketplace.*
+
+You can have both the stable version of Roo Code and a prerelease build (like Roo Code Nightly) installed simultaneously. However, it's generally recommended to enable only one at a time in your VS Code workspace to avoid potential conflicts or unexpected behavior.
