Address CodeRabbit review feedback

Fixes identified issues:
1. Fix glob expansion bugs (lines 48, 56) - removed quotes around wildcards
2. Update placeholder URL to actual GitHub raw URL
3. Improve .gitignore handling - append to existing file instead of only creating new
4. Add trap for cleanup to ensure temp directory removal even on failure
5. Remove redundant manual cleanup code

Changes:
- Line 48: "$TEMP_DIR/ccpm/"* → "$TEMP_DIR/ccpm"/*
- Line 56: commands/"* → commands/*
- Line 5: Updated URL from placeholder to real GitHub raw URL
- Added cleanup() function with trap EXIT for robust cleanup
- Enhanced .gitignore to append entries if file exists

These changes ensure the installation script is more robust and handles
edge cases properly.
