Upgrade examples to Meteor 3.5.2

[nachocodoner]

Summary

• upgrade six tracked Rspack examples to official Meteor 3.5.2 and @meteorjs/rspack 2.2.0
• regenerate Meteor package selections, npm locks, README runtime labels, and examples catalog
• keep Complex Todos node-cache lookup server-only so final Rspack does not bundle Node dependencies into browser code

Validation

• server tests: 33 passing across all six examples
• browser tests: 51 passing — Complex Todos Cypress (15), Notes Offline Playwright (13), Parties Playwright (8), Task Manager Playwright (9), Tic-Tac-Toe Playwright (6)
• source lint commands: zero errors; existing warnings remain
• git diff --check passes
