Convert to Docker template and fix validation issues

- Change from Kubernetes to Docker-based template using coder/docker base
- Remove dependency on problematic gemini module, install Gemini CLI directly
- Fix coder_parameter syntax by removing invalid 'sensitive' attribute
- Update namespace README with proper format including bio, github, avatar
- Update template README to reflect Docker approach
- Template now validates successfully with terraform validate
- Includes Code Server, terminal access, and persistent storage

-- **Type**: String
-- **Description**: Task prompt for automated Gemini execution
-- **Mutable**: Yes
-- **Default**: Empty (interactive mode)

 ## Usage
 
 ### Interactive Mode
 
-Leave the "AI Prompt" parameter empty to use Gemini CLI interactively:
-
 1. Open the Terminal app in your workspace
-2. Run `gemini` to start an interactive session
+2. Run `gemini` to start an interactive session with Google's AI
 3. Ask questions or request coding assistance
 
-### Automated Task Mode
+### Example Commands
 
-Provide a task prompt to enable automated execution:
+```bash
+# Interactive chat with Gemini
+gemini
 
-1. Set the "AI Prompt" parameter with your task description
-2. Gemini will automatically execute the task on workspace startup
-3. View task progress in the Coder UI
+# Generate code with a specific prompt
+echo "Create a simple Express.js server" | gemini
 
-## Example Prompts
+# Get help with debugging
+echo "Explain this error: TypeError: Cannot read property 'length' of undefined" | gemini
+```
+
+## What's Included
 
-- "Create a simple Express.js API with user authentication"
-- "Set up a React application with TypeScript and Tailwind CSS"
-- "Write unit tests for the existing code in this repository"
-- "Refactor the code to follow best practices and add documentation"
+- **Docker Container**: `codercom/enterprise-node:ubuntu` with Node.js pre-installed
+- **Gemini CLI**: Latest version installed via npm
+- **Code Server**: VS Code in the browser for development
+- **Terminal**: Direct shell access
+- **Persistent Storage**: Home directory persisted across workspace restarts
 
-## Security Considerations
+## Security
 
 - API keys are stored securely and masked in the UI
-- YOLO mode is disabled by default (requires manual approval for tool calls)
-- Workspace runs with non-root user (UID 1000)
-- Network policies can be applied to restrict external access
+- Container runs with appropriate user permissions
+- Network isolation through Docker
 
 ## Resources
 
-- **CPU**: 250m requests, 2 cores limit
-- **Memory**: 512Mi requests, 4Gi limit
-- **Storage**: 10Gi persistent volume
+- **Base Image**: `codercom/enterprise-node:ubuntu`
+- **Storage**: Persistent Docker volume for `/home/coder`
+- **Network**: Docker bridge with host gateway access
 
 ## Troubleshooting
 
 ### Gemini CLI Not Found
 
-The template automatically installs Node.js and npm. If Gemini CLI is not available, check the startup logs in the agent.

-Make sure the Coder Login module is properly configured and the workspace has network access to the Coder server.
+The template uses the `codercom/enterprise-node:ubuntu` image which includes Node.js. If you encounter issues, the startup script will attempt to install the latest LTS version.
