Implement wasm-solana package for Solana address generation using official Solana SDK crates (solana-pubkey, solana-keypair) compiled to WebAssembly. This is Phase 1 of replacing JavaScript Solana dependencies to mitigate npm supply chain attack risks. Architecture follows wasm-utxo patterns: - Core types wrap official Solana SDK with extension traits (PubkeyExt, KeypairExt) - Thin WASM bindings (src/wasm/*.rs) expose types to JavaScript - TypeScript wrappers (js/*.ts) provide idiomatic camelCase APIs Components: - Pubkey: base58 encoding/decoding, is_on_curve() for PDA detection - Keypair: creation from 32-byte seed or 64-byte Solana secret key format Build tooling: - Makefile matching wasm-utxo's wasm-pack workflow - TypeScript configs for ESM and CJS output Verified compatibility with BitGoJS sdk-coin-sol test vectors. Ticket: BTC-2927

actually you need to include the package in the github action test matrix

you have to set this to private: true for now, otherwise we'll break the publish action

Implement the initial wasm-solana package to support Solana address generation using Rust compiled to WebAssembly. This is the first phase of replacing JavaScript Solana dependencies (@solana/web3.js, tweetnacl) with secure Rust implementations to mitigate npm supply chain attack risks.
Architecture follows wasm-utxo patterns:
Components added:
Build tooling:
Verified compatibility with BitGoJS sdk-coin-sol test vectors to ensure byte-identical address derivation from the same secret keys.
