* harden sandbox escape vectors for bash disabled/restricted modes block git config injection (-c flag as subcommand), dangerous subcommands (config, submodule, rebase, bisect), code-executing arg flags (--exec, --extcmd), .gitattributes/.gitmodules writes, and package lifecycle scripts. add retry logic to test runner for transient failures. add security unit tests and adhoc attack tests. Co-authored-by: Cursor <cursoragent@cursor.com> * only filter subcommands in nobash, remove nobash from ui * use regex matching * iterate on tests * simplify githooks --------- Co-authored-by: Cursor <cursoragent@cursor.com>
