A replacement for the 'bazel run' command.

Why?

• 'bazel run' has inconsistent behavior about the working directory, which is often set to $(bazel info execution root). See bazelbuild/bazel#3325
  • No one wants to write --run_under="cd $PWD &&"
  • Note, https://github.com/bazelbuild/bazel/commit/7df1587ab184c5b4e0f1d7094ebb56c6167d441c fixes this in Bazel 9
• Add support for watch mode
• Ability to run multiple binaries
