Bump Codama renderer and adopt @solana/kit 6.10 (#163)

This bumps the Codama renderer and regenerates the JS client so it stays compatible with @solana/kit 6.10. The generated program plugins now return 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.

The hand-written `tokenProgram()` plugin is updated to compose the generated plugin via `extendClient` instead of an object spread. Under kit 6.10's homomorphic `ExtendedClient` type, the previous spread caused the hand-written `batch` instruction override to merge with the generated `batch` signature into a two-overload type; composing with `extendClient` cleanly replaces the `token` namespace so `batch` keeps its single intended signature (and nested batches remain a compile error).
