Problem

After installing HVE Core, users are left without a clear "first prompt" to try. The Quick Start section tells users to "Follow the guided installation (~30 seconds)" but doesn't provide an immediate next step to actually use the installed chat modes.

Proposed Solution

Add a "First Prompt" or "Try It Out" section to the Quick Start documentation with a concrete example prompt users can copy/paste immediately after installation.

Suggested Prompt Example

Help me understand what HVE Core chat modes are available and which one I should use for planning a new feature

Or alternatively:

Using the task-researcher chat mode, help me explore best practices for [topic relevant to my project]

Files to Update

• README.md - Add "First Prompt" subsection after "Automated Installation"
• docs/getting-started.md - Add "Try It Out" section after "Verifying Setup"
• .github/chatmodes/README.md - Make the Quick Start example more prominent

Acceptance Criteria

• New users have a clear, copy-pasteable prompt to try immediately after installation
• The prompt demonstrates the value of HVE Core chat modes
• Documentation is consistent across all three files
