Align monorepo configuration with Kubb structure and migrate to tsdown

[Copilot]

Update template based on Kubb repo monorepo support changes

Summary

This PR successfully updates the template repository to align with the monorepo structure and configuration used in the Kubb repository (https://github.com/kubb-labs/kubb). All changes have been implemented, tested, and verified.

Completed Changes

• Update pnpm-workspace.yaml to use the simplified format (remove comments, simplify glob patterns)
• Update turbo.json to use modern v2 configuration format (tasks instead of pipeline, add globalDependencies and globalEnv)
• Update package.json workspace configuration to match Kubb's simplified approach
• Update package.json scripts to align with Kubb's conventions (alphabetical ordering, comment scripts at top)
• Update dependency versions to match Kubb's modern versions
• Update package manager version to match Kubb's requirements (pnpm@10.24.0)
• Update node version requirement to >=20 to match Kubb
• Update all package-level package.json files with new pnpm and node versions
• Fix typecheck task to maintain build dependency (our template needs this unlike Kubb)
• Verify pnpm install works with new configuration
• Test the build and verify monorepo structure works correctly
• Run code review and address feedback
• Run security checks
• Expand README with comprehensive documentation
• Replace tsup with tsdown for build tooling (matching Kubb)

Key Improvements

1. Modern Tooling: Upgraded to latest versions of Turbo, Biome, Vitest, and other tools
2. Better Build Configuration: Turbo v2 format with explicit inputs/outputs for better caching
3. Stricter Requirements: Node >=20 and pnpm >=10 for better compatibility
4. Cleaner Configuration: Simplified workspace patterns and removed redundant comments
5. Comprehensive Documentation: Expanded README with setup guide, available scripts, and development workflow
6. tsdown Build System: Migrated from tsup to tsdown (v0.18.4) for modern TypeScript bundling, matching Kubb's approach

Build System Migration

• Renamed packages/config/tsup-config to packages/config/tsdown-config
• Updated all package build scripts from tsup to tsdown
• Converted all tsup.config.ts files to tsdown.config.ts with tsdown configuration
• Updated package exports to use .mjs (ESM) and .cjs (CommonJS) extensions
• Updated TypeScript declaration file references to .d.mts and .d.cts
• Simplified build configurations using tsdown's modern API

Testing Results

• ✅ pnpm install: successful
• ✅ pnpm run clean: successful
• ✅ pnpm run build: successful (all packages build correctly with tsdown)
• ✅ pnpm run typecheck: successful (with proper build dependencies)
• ✅ Code review: passed (1 issue found and fixed)
• ✅ Security scan: no issues (configuration files only)
