Class HTM::SequelConfig

Inherits	Object
Defined in	lib/htm/sequel_config.rb

Sequel database configuration and model loading

Uses HTM::Config for database settings. Configuration can come from: * Environment variables (HTM_DATABASE__URL, HTM_DATABASE__HOST, etc.) * Programmatic configuration via HTM.configure

Sequel is fiber-safe by design, making it ideal for async/fiber-based concurrency patterns used in HTM's job processing.
