Tutorial: migrations

This project functions as an automated maintenance system that ensures the application's configuration evolves smoothly over time without breaking user customization. It executes a series of idempotent migration scripts during startup to update deprecated data formats, move settings between global and local scopes, and standardize model aliases (like updating "Sonnet" to its latest version). By strictly gating these changes based on user segmentation (such as subscription tier), it guarantees that upgrades are applied safely and only to the eligible users.
