…m-solana Adds WASM-based transaction parsing that eliminates @solana/web3.js dependency for the decoding/explain flow. The WASM library (@bitgo/wasm-solana) handles all instruction decoding, and a simple type mapper converts to BitGoJS format. Key changes: - Add wasmInstructionMapper.ts: Maps WASM types to BitGoJS InstructionParams - Combines CreateAccount + StakeInitialize + Delegate -> StakingActivate - Combines CreateAccount + NonceInitialize -> CreateNonceAccount - Handles Jito staking (StakePoolDepositSol, StakePoolWithdrawStake) - Handles standalone delegate for re-delegation - Add WasmTransaction class (wasm/transaction.ts) for WASM-only parsing - Update wasmInstructionCombiner.ts as clean entry point - Update sol.ts explainTransactionWithWasm to use bytes-based API - Remove wasmInstructionAdapter.ts (no longer needed) NO @solana/web3.js dependencies in the new parsing flow. TICKET: BTC-0

Add ESM alias for @bitgo/wasm-solana similar to wasm-utxo to ensure proper WASM initialization in browser bundles. Ticket: BTC-0
Introduces WASM-based transaction building for testnet (tsol) via @bitgo/wasm-solana, with zero @solana/web3.js runtime dependency. ## Architecture Testnet (WASM path - no web3): - customInstructionBuilder stores versioned data on _versionedTransactionData - buildVersionedWithWasm() delegates to wasm/builder.ts - Nonce injection via wasm/builder.injectNonceAdvanceInstruction() Mainnet (legacy path - unchanged): - customInstructionBuilder stores on Transaction class + injects nonce - buildVersionedTransaction() reads from Transaction class - Original behavior preserved ## Key files - wasm/builder.ts: buildWasmTransaction(), buildVersionedWasmTransaction() - wasm/builder.ts: injectNonceAdvanceInstruction() (pure WASM constants) - customInstructionBuilder.ts: testnet/mainnet branching for storage TICKET: BTC-0
