This commit replaces all hardcoded message type integers (0, 1, 2, 3, 4,
5) with named constants from a new MessageType module, improving code
readability and maintainability across the codebase.
The commit adds a complete example environment configuration file
documenting all available settings for BotServer, including logging,
database, server, drive, LLM, Redis, email, and feature flags.
Also removes hardcoded environment variable usage throughout the
codebase, replacing them with configuration via config.csv or
appropriate defaults. This includes:
- WhatsApp, Teams, Instagram adapter configurations
- Weather API key handling
- Email and directory service configurations
- Console feature conditionally compiles monitoring code
- Improved logging configuration with library suppression
The sqlx database library has been removed from the project along with
associated database-specific code that was no longer being used. This
includes removal of various sqlx-related dependencies from Cargo.lock
and cleanup of database connection pool references.
