Make watch behave the same way as run when executed from a specific package directory

[Ugzuzg]

Goals

1. Identical behaviour for run and watch when run from a specific package directory, with the only difference being that watch watches

Non-goals

No response

Background

Currently, if I cd packages/a and run turbo run build, it will only use that package's build command as a target, only running its dependencies and then the build of that package.
If I cd packages/a and run turbo watch build, it suddenly looks for all build commands in the workspace, and I have to add --filter to limit the scope of the watcher.

Proposal

Make run and watch the same.

Hey, we've now got this done in #9404. It will be a part of the next canary release (v2.2.4-canary.9) and later.

Thanks for suggesting!
