[engine] Rename Options.Root to Options.Dir

For consistency with Ic9aef678e2cb518a81ff2f36f3bec6fda969675d, rename
the Root field to Dir, since shac now uses git to locate the root
directory, which may differ from (but will always be a parent of) the
directory specified by the Dir field.

Road map

Planned features/changes, in descending order by priority:

  • [x] Configuring files to exclude from shac analysis in shac.textproto
  • [x] Include unstaged files in analysis, including respecting unstaged shac.star files
  • [x] Automatic fix application with handling for conflicting suggestions
  • [ ] Provide a .shac cache directory that checks can write to
  • [ ] Mount checkout directory read-only
    • [x] By default
    • [ ] Unconditionally
  • [ ] Give checks access to the commit message via ctx.scm
  • [ ] Built-in formatting of Starlark files
  • [ ] Configurable “pass-throughs” - non-default environment variables and mounts that can optionally be passed through to the sandbox
  • [ ] Add glob arguments to ctx.scm.{all,affected}_files() functions for easier filtering
  • [ ] Filesystem sandboxing on MacOS
  • [ ] Windows sandboxing
  • [ ] Testing framework for checks
