Migrate an existing app to Rspack

Rspack compiles app code; Meteor builds Atmosphere packages and assembles the bundle. Keep packages, but audit their architecture and browser dependencies.

Prerequisite: Meteor 3.4+. Recommended before activation: enable "meteor": { "modern": true } and fix Babel fallbacks. For setup and helpers, use meteor-modern-build-stack.

Match @meteorjs/rspack to the Meteor release, not to @rspack/core or @rspack/cli:

Meteor rspack @meteorjs/rspack Capability boundary
3.4 1.0.0 1.0.0 Base integration and helpers.
3.4.1 and 3.5 1.1.0 2.0.1 Adds v2 helpers and inherited TOOL_NODE_FLAGS.
3.5.1 1.2.0 2.1.0 Revised client polyfills and extension discovery.
3.5.2 1.3.0 2.2.0 Dependency diagnostics, mode isolation, full-app/TLA and cache fixes.
3.6-beta.0 1.4.0-beta360.0 3.0.0-beta.1 Rspack 2.2.0 and workspace-aware installs.
