harden sandbox escape vectors for bash disabled/restricted modes (#257)
* 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.
