Tree-shaking

[catmcgee]

[do not pick up this issue yet]

go through the entire lib and

• import @solana/[whatever] instead of @solana/kit , eg
  • RPC client & transport → @solana/rpc, @solana/rpc-transport-http (and @solana/rpc-api, @solana/rpc-types only where needed)
  • Subscriptions → @solana/rpc-subscriptions
  • Transactions (compile/sign) → @solana/transactions
  • Transaction messages (build/transform) → @solana/transaction-messages
  • Signers → @solana/signers
  • Accounts fetch/decode → @solana/accounts, @solana/codecs, @solana/sysvars
  • Error utils → @solana/errors

Add ESLint rule: disallow @solana/kit as an import source

Add "sideEffects": false except for any files that actually run code on import (list those explicitly) (I don’t know what these are yet)

Always use named exports
