grunt pre-commit does not exist in perennial/perennial-alias

[samreid]

While working on #412 I observed that you cannot run grunt pre-commit in perennial. Instead you have to run sage run ../chipper/js/grunt/tasks/pre-commit.ts. @zepumph how should we proceed?

[zepumph]

I want to discuss this a bit more. It should be up to the repo to determine what tasks it supports. Likely we will need some logic in chipper and some in perennial though, since lint-all is appropriate in chipper, but in perennial it should just be lint. Same for report-media.

In discussion with @zepumph, we think it would be nice for perennial to have grunt pre-commit with a subset of steps that are appropriate for perennial. Then chipper can layer on more tasks that are appropriate for that level.

But we also saw that perennial's precommit hooks run out of chipper, and that is not good. So we should schedule time to work on this.

For me, the important part is that precommit hooks still run, and you can run them with sage run. I'm not planning to work on this independently, but let me know if you would like assistance or collaboration. Self-unassigning until then.
