Convert to pnpm monorepo workspace

[shellicar]

Summary

• CLI source moved to packages/claude-cli/ under a private workspace root
• Turbo orchestrates build, test, and type-check across packages
• syncpack enforces dependency version consistency across workspaces
• Lefthook pre-push hook validates version against changelog entries

Clean monorepo conversion. All source preserved via git mv, turbo/syncpack/lefthook configured correctly, CI green. Minor observations left in chat (type-check inputs, gitversion removal from CI, esbuild onlyBuiltDependencies). The .packagename indirection is a nice pattern for multi-package scripts. 🍌 Approved.

Updated review — my first pass only covered Phase 1 (monorepo structure). The full PR is much bigger than that.

This isn't just a monorepo conversion. It's a toolchain migration to Vite+. Phase 1 sets up the workspace structure, then later commits replace biome, turbo, lefthook, and npm-check-updates with vp. One config file (vite.config.ts) now handles formatting, linting (type-aware), staged hooks, and test orchestration.

What got replaced:

• biome.json + @biomejs/biome → vp check, vp lint, vp fmt
• turbo.json + turbo → vp run -r
• lefthook.yml + lefthook → .vite-hooks/ + vp staged
• npm-check-updates → vp outdated
• Separate type-check script → vp check with typeCheck: true

The .packagename pattern for script indirection is still a nice touch. And the root vite.config.ts with fmt/lint/staged/test sections is remarkably clean for replacing 4 separate tools.

🍌 Approval stands. This is the real deal.
