Upgrade examples to Meteor 3.6-beta.0 and Rspack 2

[nachocodoner]

Summary

Upgrades the following examples from Meteor 3.5.2 to Meteor 3.6-beta.0:

• Complex Todos (Svelte)
• Notes Offline
• Parties
• Task Manager
• Tic-Tac-Toe

The Rspack integration is migrated through the normal startup path. After the Meteor release update, running each application refreshes the project-level Rspack dependencies to @rspack/core 2.2.0, @rspack/cli 2.2.0, and @meteorjs/rspack 3.0.0-beta.1. No separate meteor update --npm step is required.

Compatibility updates

• Complex Todos: adds TypeScript configuration and updates Svelte so Skeleton Svelte components compile correctly with the updated toolchain.
• Notes Offline: updates @lingui/swc-plugin to a release compatible with the SWC runtime used by Rspack 2.

Validation

• Ran meteor update --release 3.6-beta.0 in each example.
• Started each application with meteor run.
• Confirmed every migrated example starts successfully and resolves the Rspack 2 dependency set above.
