CTX7-854: Migrate to pnpm monorepo

[fahreddinozcan]

This pull request restructures the repository into a monorepo with support for multiple packages, introduces configuration and tooling for consistent development workflows, and sets up the foundation for both MCP server and SDK packages. The changes include monorepo setup, package isolation, and standardized linting and formatting.

Monorepo and Package Structure:

• Converted the repository into a monorepo using pnpm workspaces, with a new root package.json describing the monorepo and specifying packages/* as workspaces. The root package is now private and focused on documentation tools and SDKs.
• Created a dedicated @upstash/context7-mcp package in packages/mcp with its own package.json, dependencies, scripts, and metadata, isolating the MCP server implementation from the root.

CTX7-854 Context7 TS SDK

Looks good overall, I am just curious about how we will update the workflows once we have other packages

Also, did you try the release workflow? I didn't try in detail, just built the package and ran npm pack --dry-run to see what's included in the tarball. It included dist and package.json. License and README were missing.

We have license and README in the current release

We could copy the README at directory in the build script instead of duplicating the README maybe, to avoid having to maintain two files at the same time 8e8f2f5

• Adding an explicit type assertion as SearchResponse after parsing JSON is good, but the response isn't validated against the SearchResponse interface. Consider adding runtime validation using Zod (which is already a dependency) to ensure the API response matches the expected type structure before casting.
