solana-sdk is dead, long live the Solana SDK!
summary
Solana SDK is split into roughly 100 component crates, moved into the Anza repo and decoupled from validator releases; upgrade to 2.2.1 and replace solana-program with component crates to cut builds from 147 → 21 crates and compile time from ~24 seconds to under 3 seconds. Expect v3 with careful semver, shared base types for frameworks, a new zero‑copy serialization library, and more selective dependency cleanup.
