Make effect peerDependency

[mikearnaldi]

Effect is currently loaded via utils as a dependency while it should be loaded as peerDependency. Linking libs as deps is generally unadvisable for any dependency but poses a critical risk for effect (and its ecosystem packages) in particular given that it doesn't work if multiple copies are loaded.

Note that multiple copies will be loaded any time a user of the lib installs a different version of effect (even a patch) in a child project, that isn't the case for peerDependencies with a set range of acceptable versions
