Walkthrough

Converts the repository into a Cargo workspace, adds new program-runtime and transaction-context crates, introduces a solana-account crate with CoW accounts, refactors SVM core execution APIs and tests, updates example programs, and removes legacy docs, JSON-RPC examples, and PayTube demos.
