fix(eve): ignore framework marker packages

[glucas1103]

Description

Closes #1235.

Eve's authored-module, immutable-generation, Workflow, and Nitro host bundles all execute on the server, but some paths currently preserve server-only, client-only, and Next.js's compiled variants as runtime imports. The marker package can then throw while the generated Node function is loading.

This change introduces one shared pseudo-package bundler plugin that resolves those four framework-only markers to empty virtual modules and wires it into every Eve-owned server bundling path. It also replaces the Workflow-only special case with the shared implementation, documents the behavior, and adds a patch changeset.
