CI: Add program and all extra steps (#13)

* CI: Add program and all extra steps

#### Problem

The token program now lives in its program-specific repo, but no part of
it is being exercised by CI.

#### Summary of changes

Integrate the token program properly into CI. This includes:

* add it to the Cargo workspace, and removing spl-token-client, since
  it's currently empty
* run lint / format / test on the program
* run spellcheck / audit / semver checks on the Rust packages
* move rust scripts to `scripts/rust` and make them reusable
* update to Solana 2.1 and proper rust toolchains

* Move JS scripts around, build program too
