Add function to select and accept best friend request

[konard]

Summary

Implements a function that selects and accepts the best match from incoming friend requests based on the following criteria:

• User is online - Only considers users who are currently online
• User has maximum common friends - Prioritizes users with the most mutual friends
• User is not blocked or deactivated - Filters out deactivated or blocked accounts

Implementation Details

Files Added

• Application/acceptBestFriendRequest.js - VK API execute script that:

  • Fetches up to 100 incoming friend requests with extended information
  • Filters for online, non-deactivated users
  • Calculates mutual friends count for each eligible user
  • Selects the user with the maximum mutual friends
  • Accepts the friend request from the selected user

• accept-best-friend-request.sh - Shell script to invoke the function via VK API

• experiments/test-best-friend-request-logic.js - Test script that validates the selection algorithm with mock data

How It Works

The algorithm iterates through all incoming friend requests and:

1. Checks if the user is not deactivated
2. Checks if the user is currently online
3. For eligible users, counts mutual friends
4. Tracks the user with the maximum mutual friends
5. Accepts the friend request from the best match

Usage

./accept-best-friend-request.sh
