Fix example crashes when monetization blocks research operations

[Copilot]

Pull Request

Description

Example files crashed when research operations were blocked by free tier monetization limits. The code attempted to access result dictionary keys (topic, aggregated_sources) that don't exist in error responses. Two examples also failed to import the megabot module due to missing path configuration.

Fixes issue with example files crashing on monetization-blocked operations.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Performance improvement
• Code refactoring
• Tests
• CI/CD changes

Changes Made

examples/basic_usage.py & examples/advanced_research.py:

• Added error checking before accessing result fields to handle monetization blocks gracefully
• Used .get() for optional keys like aggregated_sources

# Before (crashes on error)
research = await bot.research("topic", depth="medium")
print(f"Topic: {research['topic']}")

# After (handles errors)
research = await bot.research("topic", depth="medium")
if 'error' in research:
    print(f"Research error: {research['error']}")
else:
    print(f"Topic: {research['topic']}")

examples/validation_example.py & examples/monetization_example.py:

• Added sys.path.insert() to resolve module import failures when running examples directly

How Has This Been Tested?

• All 42 unit tests pass (0.47s)
• All 5 example files execute without errors
• Main demo runs successfully
• CodeQL security scan shows 0 vulnerabilities

Test Configuration:

• Python version: 3.12.3
• OS: Linux (Ubuntu)
• MEGAGENT version: 1.2.0

Pull Request Overview

This PR enhances the example files by adding consistent error handling for research operations. The changes ensure that example scripts gracefully handle error responses from the MegaBot's research functionality, improving the robustness and user experience of the example code.

Key Changes:

• Added error checking for research results in basic_usage.py and advanced_research.py
• Added defensive .get() method usage for optional fields to prevent KeyError exceptions
• Ensured consistent sys.path manipulation across example files (validation_example.py and monetization_example.py already have this pattern)
