Fix CI: Restore explicit build order for workspace packages

The research showed the root cause - TypeScript couldn't find @debugmcp/shared
because it wasn't being built before the packages that depend on it.

Solution: Explicitly build shared first, then adapter-mock, then adapter-python.
This ensures all .d.ts files exist when TypeScript tries to resolve them.

The shared package already has:
- Proper index.ts with all exports
- Correct main and types fields in package.json
- Properly configured exports field

This should finally fix the TS2307 errors in CI.
