Applies whatever plugins a project's target.exs newly lists that its
plugin.exs hasn't recorded yet — see
docs/superpowers/specs/2026-08-26-plugin-ecosystem-design.md.
Never re-resolves or upgrades an already-recorded plugin, even when a better-matching archive now exists for it — that comparison is explicitly out of scope, per the design doc's "Explicitly out of scope" section.
Summary
Functions
Applies every plugin type listed in target's target.exs that is not
already recorded in its plugin.exs. Returns the types actually applied,
in target.exs's own order.

sync is called once per newly-listed type, immediately before that
type is installed — never once for the whole batch up front, so a later
type's sync failure never undoes an earlier type's already-completed
install. Injectable for the same reason Capstone.New.Bootstrap.run/3's
effects.sync is: a test exercising a local, unpublished fixture type
should not depend on network access.
