https://github.com/user-attachments/assets/a77aa941-da48-4c30-8e14-587516c19ac4 Added a new feature that allows the bot to introduce itself when added to a Slack channel. This includes a welcome message and a detailed thread reply outlining its capabilities. The implementation includes new utility functions for handling the welcome event, managing welcome state, and posting messages. Updated relevant logic functions to support this feature, ensuring the bot can provide a seamless introduction to users in new channels. - Introduced `slack-channel-welcome` logic function. - Added constants for welcome message text. - Implemented event parsing and handling for `member_joined_channel`. - Updated `slack-events-resolver` to route welcome events appropriately.
