🎯 What: The run function in src/main.rs was overly long and complex, handling multiple commands in a single large match statement. This refactoring extracts the logic for each command into its own dedicated helper function.

💡 Why: Breaking down the 100+ line run function makes the codebase easier to maintain, read, and test. It separates the argument parsing and routing from the specific implementation details of each CLI command.

Verification: Verified by compiling the project (cargo check), formatting the code (cargo fmt), and successfully running the relevant unit tests and CLI tests (cargo test --lib --bin praefectus, cargo test --test cli) within the expected isolated sandbox environment.

Result: The run function is now much more concise and delegates its work efficiently, achieving the desired code health improvement without changing any user-facing functionality.

Note

Low Risk
Mechanical extraction with no logic changes; CLI behavior remains covered by existing tests.

Overview
Refactors the praefectus CLI so run only routes subcommands instead of embedding their full implementations.

Each former match arm (status, capabilities, observe, surfaces, observe-surface) is now a dedicated run_* helper with the same argument checks, Engine/NativeExecutor usage, timeouts, and JSON serialization as before. No intended CLI or protocol behavior change.

In tests/cli.rs, fixes indentation in the test helper that pipes stdin to the spawned CLI process.

Reviewed by Cursor Bugbot for commit 00d4546. Configure here.

Extracted the individual command match arms within `run` in `src/main.rs` into standalone helper functions (`run_status`, `run_capabilities`, `run_observe`, `run_surfaces`, `run_observe_surface`) to improve code health, readability, and maintainability.
