Bump Codama renderer and adopt @solana/kit 6.10 (#344)

* Bump Codama renderer and adopt @solana/kit 6.10

This bumps the Codama renderer and regenerates the modern JS client so it stays compatible with @solana/kit 6.10. The generated program plugin now returns the homomorphic `ExtendedClient` type (introduced in kit 6.10) instead of the previous `Omit<T, ...>` intersection, and the client's kit floor is raised to ^6.10.0.

* Fix package.json indentation
