do something useful for `aspect build` or `aspect test`

[alexeagle]

Bazel's behavior is pretty dumb

alexeagle@system76-pc:~/Projects/aspect-cli$ bazel build
WARNING: Usage: bazel build <options> <targets>.
Invoke `bazel help build` for full description of usage and options.
Your request is correct, but requested an empty set of targets. Nothing will be built.

alexeagle@system76-pc:~/Projects/aspect-cli$ bazel test

Proposal

When interactive: bazel build prompts

what would you like to build? all targets in current folder /path/to (this is the workspace-relative path you're in) all targets beneath current folder specific target patterns

if you choose target patterns, we help you select them

and then prompts

remember this for next time?
