* Refactor all completion logic into `NuCompleter` This is the next step to improving completions. Previously, completion logic was scattered about (`FilesystemShell`, `NuCompleter`, `Helper`, and `ShellManager`). By unifying the core logic into a central location, it will be easier to take the next steps in improving completion. * Update context.rs Co-authored-by: Jonathan Turner <jonathandturner@users.noreply.github.com>
