Pull request overview

Adds a repository-scoped bash execution tool to the dub ai ask assistant so it can fetch real command output directly from the current repo while applying safety constraints.

Changes:

• Introduce a local bash-tool sandbox implementation with command/file access guards.
• Wire the bash tool into askAi() and limit tool iterations via stopWhen.
• Document the new bash tool behavior and update quickstart text.
