V2 RC

Remove duplicate devDependencies across workspace

Moved shared tooling to root:
- typescript, eslint, prettier, vitest, typedoc
- All TypeScript ESLint plugins
- ts-node and @types/node

Kept package-specific devDependencies in packages:
- Main package: AWS SDK test dependencies, deep-equal
- Examples: AWS types and deep-equal types

This eliminates unnecessary duplication while maintaining
functionality through npm workspace hoisting.
