Convert from Bun to Node.js

- Replace bun-pty with node-pty
- Update all shebangs from bun to node
- Replace Bun.build() with esbuild
- Add bun-compat.ts for Bun API compatibility layer
- Update all package.json files to remove catalog: references
- Change package manager from bun to pnpm
- Update GitHub Actions to use Node.js instead of Bun
- Add tsx for TypeScript execution
- Update tsconfig to use @tsconfig/node22
- Add Windows Server setup and cleanup scripts

This migration is necessary because Bun has memory alignment bugs
in virtualized Windows environments that cause crashes.

+# Running OpenCode on Windows Server 2022 with Node.js
+
+Since Bun has memory alignment issues in virtualized environments, you can run OpenCode directly with Node.js instead.
+
+## Prerequisites
+
+1. **Install Node.js 20 or later** on your Windows Server:
+   ```powershell
+   # Download and install Node.js LTS
+   winget install OpenJS.NodeJS.LTS
+   # Or download from: https://nodejs.org/
+   ```
+
+2. **Install pnpm** (package manager):
+   ```powershell
+   npm install -g pnpm
+   ```
+
+## Installation
+
+1. **Clone the repository**:
+   ```powershell
+   git clone https://github.com/mattbaylor/opencode.git
+   cd opencode
+   ```
+
+2. **Install dependencies**:
+   ```powershell
+   pnpm install
+   ```
+
+3. **Run OpenCode**:
+   ```powershell
+   # Run directly with tsx (TypeScript executor)
+   pnpm --filter opencode exec tsx src/index.ts
+   
+   # Or create an alias/function in your PowerShell profile
+   ```
+
+## Creating a PowerShell Function (Optional)
+
+Add this to your PowerShell profile (`$PROFILE`):
+
+```powershell
+function opencode {
+    $OpencodeDir = "C:\path\to\opencode"  # Update this path
+    Push-Location $OpencodeDir
+    pnpm --filter opencode exec tsx packages/opencode/src/index.ts $args
+    Pop-Location
+}
+```
+
+Then you can just run `opencode` from anywhere.
+
+## Alternative: Use WSL2
+
+If you have WSL2 enabled on Windows Server 2022, you can run the Linux version of OpenCode which doesn't have these virtualization issues:
+
+```bash
+# In WSL2
+git clone https://github.com/mattbaylor/opencode.git
+cd opencode
+# Use the original bun-based build or Node.js
+```
+
+## Why This Works
+
+- Node.js doesn't have the memory alignment issues that Bun has in VMs
+- You're running from source with TypeScript execution (tsx)
+- No need to create standalone binaries
+- Easier to update and debug
