Summary

  • Add todo, unimplemented, and print_stderr to the workspace's denied clippy restriction lints so accidental scaffolding code and stray stderr prints can't slip into production.
  • Replace existing todo!() / unimplemented!() calls with explicit panic!("… is not implemented yet") messages.
  • Route most eprintln!s through tracing (error/warn/debug levels), and #[expect] the legitimate cases (panic hook in the napi binding, debug_print helpers, integration tests, the example, tasks/ls_lint).

It seems like our usages of eprintln is not correct, let's discuss this in a meeting.

## Summary

- Add `todo`, `unimplemented`, and `print_stderr` to the workspace's denied clippy restriction lints so accidental scaffolding code and stray stderr prints can't slip into production.
- Replace existing `todo!()` / `unimplemented!()` calls with explicit `panic!("… is not implemented yet")` messages.
- Route most `eprintln!`s through `tracing` (error/warn/debug levels), and `#[expect]` the legitimate cases (panic hook in the napi binding, `debug_print` helpers, integration tests, the example, `tasks/ls_lint`).
