Auto-follow artist on coin purchase

[dylanjeffers]

Summary

This PR adds functionality to automatically follow an artist when a user purchases their coin through the Jupiter swap interface.

Key Changes

• Added autoFollowArtistOnCoinPurchase function that:

  • Fetches the artist coin metadata after a successful swap
  • Resolves the coin's owner (artist)
  • Automatically follows the artist if the user isn't already following them
  • Gracefully handles errors and skips non-artist coins

• Integrated auto-follow logic into the useSwapCoins hook's onSuccess callback to trigger after successful coin purchases

• Added ARTIST_COIN_PURCHASE to the FollowSource enum in Analytics to track the source of these auto-follows

• Added necessary imports and dependencies:

  • useDispatch from react-redux
  • useFollowUser hook for executing the follow action
  • coinFromSdk adapter for coin data transformation
  • NON_ARTIST_COIN_MINTS constant to filter out non-artist coins
  • getArtistCoinQueryFn for fetching coin metadata
  • entityCacheOptions for query configuration

Implementation Details

• The auto-follow is non-blocking and wrapped in error handling to prevent swap failures
• Skips execution if the output mint is not an artist coin or if the user already follows the artist
• Uses the existing query client to fetch coin data and check follow status
• Reports any errors to Sentry for monitoring
