Fix command examples and improve step-by-step guidance in PRZEWODNIK.md

[Copilot]

Problem

The PRZEWODNIK.md file contained incorrect specialization IDs in command examples, causing errors when users tried to follow the guide. Commands like python3 graf_tools.py path ai failed because the actual specialization ID is ai_data_science.

Additionally, the guide lacked clear step-by-step instructions for students and coordinators on how to effectively use the graf_tools.py script.

Changes

1. Corrected All Specialization Command Examples

Before:

python3 graf_tools.py path ai              # ❌ Error: Unknown specialization
python3 graf_tools.py path gaming          # ❌ Non-existent
python3 graf_tools.py path networking      # ❌ Wrong ID

After:

python3 graf_tools.py path ai_data_science    # ✅ Works correctly
python3 graf_tools.py path web_networking     # ✅ Works correctly
python3 graf_tools.py path embedded_systems   # ✅ Works correctly
python3 graf_tools.py path software_engineering
python3 graf_tools.py path signal_processing

2. Updated AI Specialization Example Output

Replaced the minimal, outdated example output with complete, accurate results from ai_data_science, showing:

• All relevant semesters (1, 2, 3, 5)
• Current hierarchical format: Semestr → Przedmiot → Koncept
• Enhanced interpretation explaining what students should focus on in each semester

3. Enhanced Step-by-Step Guidance

For Students:

• Restructured into clear 3-step process (Krok 1, 2, 3)
• Added explanations for what each command does
• Added guidance on how to interpret results

For Coordinators:

• Added two methods for checking student prerequisites (manual + automatic)
• Expanded "Adding New Specialization" from 3 to 6 detailed steps with validation
• Added practical example using the specializations command

4. Added New Practical Examples

• Web development specialization example showing web_networking path
• Coordinator example demonstrating how to help students explore options

Verification

All commands have been tested and verified working:

• ✅ python3 graf_tools.py specializations
• ✅ python3 graf_tools.py path ai_data_science
• ✅ python3 graf_tools.py path web_networking
• ✅ python3 graf_tools.py path embedded_systems
• ✅ python3 graf_tools.py path software_engineering
• ✅ python3 graf_tools.py path signal_processing
• ✅ python3 graf_tools.py validate

<issue_title>Popraw treść w pliku Przewodnik.md</issue_title>
<issue_description>@Copilt popraw treść w pliku Przewodnik.md, przede wszystkim tam, gdzie są wywołania komendy 'python3 graf_tools.py path ai' wstaw 'python3 graf_tools.py path ai_data_science' i adekwatnie popraw przykładowe wyniki jej działania zapisane w tym pliku. Adekwatnie popraw pozostałe wywołania komendy zaczynającej się od 'python3 graf_tools.py path'. Skup się na tym, aby krok po kroku pokazać potencjalnym użytkownikom, w tym przypadku studentom i koordynatorom programów dydaktycznych, jak skorzystać z dostępnych możliwości skryptu 'graf_tools.py'.
