ADDED Requirements

Requirement: Maintain 100% Test Coverage

The refactoring SHALL preserve all existing unit and integration tests, ensuring no functionality is broken during the structural changes.

Scenario: Running test suite

• WHEN the cargo test --workspace command is executed
• THEN all tests across rusty-claude-cli must pass successfully

Requirement: Modular Separation

The system SHALL separate the monolithic main.rs file into cohesive modules: models, error, repl, and render.

Scenario: Module verification

• WHEN inspecting the rusty-claude-cli/src/ directory
• THEN new files (models.rs, error.rs, repl.rs) exist and main.rs is reduced to primarily act as an entrypoint routing module.
