fix: replace print() with debugPrint() in SWOCScreen and LinuxFoundation

[adityashirsatrao007]

Description

Removes or replaces debug print() statements in two program screens.

Problem

Both screens used bare print() statements that run in production:

social_winter_of_code.dart — _loadProjects() method:

print('Loaded projects from $path: ${list.length}');  // runs for every JSON file loaded
print('Error: JSON data is null or empty in $path');
print('Error loading projects from $path: $e');

linux_foundation.dart — bookmark toggle & search callbacks:

print("Adding");     // runs on every bookmark add
print("Deleting");   // runs on every bookmark remove
print("value is $value");  // runs on every search submit

Fix

• SWoC: Removed the success log (not needed), replaced error logs with debugPrint() (stripped in release builds automatically by Flutter)
• Linux Foundation: Removed all 3 statements entirely (no diagnostic value)

Related Issue

Fixes #417 (Improved linting and code quality)

Type of Change

• Bug fix (removing/replacing debug code from production)

Checklist

• No functional changes
• debugPrint() is Flutter's recommended replacement for print() in widget code
• Tests pass
• No lint warnings introduced
