ADDED Requirements

Requirement: Modular CLI Core

The rusty-claude-cli application SHALL be structured into multiple distinct modules (cli, config, execution, permissions, diagnostics, ui) instead of a single monolithic main.rs file.

Scenario: Unchanged Application Behavior

• WHEN the application is compiled and executed
• THEN all CLI commands, arguments, and interactive features function exactly as they did before the refactoring.

Scenario: Unchanged Test Suite

• WHEN cargo test is run for the rusty-claude-cli crate
• THEN all existing unit and integration tests pass successfully.

Scenario: Code Compilation

• WHEN cargo check is run
• THEN the crate compiles without any new warnings or errors related to module structure or unresolved imports.

Scenario: Code Formatting

• WHEN cargo fmt --all is run
• THEN the new module structure complies with the project's formatting standards.
