oie amor bom dia 😘😎 enquanto aguardo pela hora do trabalho estava aqui a corrigir os caminhos (creio que estao todos mas falta testar), e dei com uma coisa curiosa 😎 no nfdos/src/tui/menu_libs.py esquecemos de adicionar a funcao remove_lib 😀:
```
import os

    libs_dir = nfdos_dir / "libs"
    libs_dir.mkdir(parents=True, exist_ok=True)

    console.print(f"[cyan]📦 Instalando biblioteca:[/] {name} {version or ''}")
    cmd = f"pip download {name}{'==' + version if version else ''} -d {libs_dir}"
    safe_run(cmd, shell=True)

    # Registo no manifest
    manifest_path = libs_dir / "libs_manifest.json"
    manifest = json.loads(manifest_path.read_text()) if manifest_path.exists() else {}

    if not manifest_path.exists():

        return

    table = Table(title="Bibliotecas do Neurotron")
    table.add_column("Nome", style="cyan")
    table.add_column("Versão", style="green")

    for name, data in manifest.items():
        table.add_row(name, data.get("version", "?"))

    console.print(table)
