feat: add hello world file with PRP documentation

[Wirasm]

Summary

This PR creates a simple text file named hello-world-1.txt in the root directory containing the text "Hello from parallel work order 1!". This feature serves as a demonstration of basic file creation functionality and can be used for testing parallel work order execution systems.

Changes

• feat: add hello world file with PRP documentation

Files Changed

• PRPs/features/completed/create-hello-world-1-file.md - Complete PRP documentation for the feature
• hello-world-1.txt - The created hello world file

Implementation Details

This implementation follows the PRP documented in PRPs/features/completed/create-hello-world-1-file.md. The solution is straightforward: create a text file with predefined content using direct file operations.

Key Design Decisions:

• Kept the implementation extremely simple per KISS principle (no over-engineering)
• Followed YAGNI by not adding unnecessary validation or error handling
• Designed for parallel execution compatibility (won't conflict with hello-world-2, etc.)

Testing

• File hello-world-1.txt exists in the root directory
• File contains exactly the text: "Hello from parallel work order 1!"
• File is readable and has appropriate permissions
• File appears in git status
• No errors occurred during file creation
• File content verified with validation commands

Validation Commands

All validation commands from the PRP have been executed successfully:

# Verify file exists
ls -la hello-world-1.txt

# Display file content
cat hello-world-1.txt

# Verify exact content match
test "$(cat hello-world-1.txt)" = "Hello from parallel work order 1!" && echo "Content matches!"

# Check git status
git status hello-world-1.txt
