fix(ns-openapi-3-0): correct sideEffects path to refractor/inspect

The sideEffects field still pointed at src/refractor/registration.mjs
and .cjs, which were renamed to inspect.mjs/.cjs. Every other namespace
package was migrated at the time of the rename; this one was missed.

src/index.ts re-exports the element classes from refractor/inspect.ts,
which installs the static fixedFields getters via Object.defineProperty
before re-exporting. Marking that module side-effect-free lets bundlers
rewire the re-export straight to src/elements/*, so inspect is never
evaluated and the getters are never installed.

Downstream this surfaces at module load: apidom-reference builds its
Components field maps from fixedFields(ComponentsElement, { indexed:
true }) at module scope, which yields {} in a bundled build and throws
a TypeError on the first field lookup.
