//! Sources Module
//!
//! Manages all source types for bots including:
//! - Repositories (GitHub, GitLab, Bitbucket)
//! - Apps (HTMX apps created with CREATE SITE)
//! - Prompts (System prompts and templates)
//! - Templates (Bot packages .gbai)
//! - MCP Servers (Model Context Protocol servers from mcp.csv)
//! - LLM Tools (Available tools for LLM invocation)
//! - Models (Configured AI models)
//!
//! MCP servers are configured via `mcp.csv` in the bot's `.gbai` folder,
//! making their tools available to Tasks just like BASIC keywords.
