Architecture: Unified Configuration and Stateful Execution

[db-tycoon-stephen]

The CLI should act as a transparent window into the 'tycoon.yml'. Changes to the configuration (e.g., adding a new source in YAML) should be automatically detected by the CLI during execution, triggering only the necessary delta-updates (stateful execution). The goal is to make the terminal and the YAML file feel like a single, unified interface.
