Unreleased

The Elm Architecture (TEA): Implemented the core Model-View-Update (MVU) runtime. Use RatatuiRuby::Tea.run(model, view: ..., update: ...) to start an interactive application with predictable state management.
Async Command System: Side effects (database, HTTP, shell) are executed asynchronously in a thread pool. Results are dispatched back to the main loop as messages, ensuring the UI never freezes.
Ractor Safety Enforcement: The runtime strictly enforces that all Model and Message objects are Ractor-shareable (deeply frozen). This guarantees thread safety by design and prepares for future parallelism.
Flexible Update Returns: The update function supports multiple return signatures for developer ergonomics:
[Model, Cmd] — Standard tuple.
Model — Implicitly [Model, Cmd::None].
Cmd — Implicitly [CurrentModel, Cmd].
Startup Commands: RatatuiRuby::Tea.run accepts an init: parameter to dispatch an initial command immediately after startup, useful for loading initial data without blocking the first render.
View Validation: The view function must return a valid widget. Returning nil raises RatatuiRuby::Error::Invariant to catch bugs early.

First Release: Empty release of ratatui_ruby-tea, a Ruby implementation of The Elm Architecture (TEA) for ratatui_ruby. Scaffolding generated by ratatui_ruby-devtools.
