 * Offline reimplementation of `OnchainPM.computeScriptHash()`.
 *
 * Avoids a live RPC call so scripts can be built and hashed without a running
 * node. Matches the on-chain `pure` function exactly:
 *
 * ```solidity
 * keccak256(abi.encodePacked(
 *   keccak256(abi.encodePacked(commands)),
 *   _hashBitmapSlots(state, stateBitmap),
 *   stateBitmap,      // uint128 — 16 bytes packed
 *   state.length,     // uint256 — 32 bytes packed
 *   keccak256(abi.encode(callbacks))
 * ))
 * ```
 *
 * **Key property**: state slots whose bitmap bit is 0 (runtime) are excluded
 * from the hash. Runtime values can therefore change at execution time without
 * invalidating the Merkle proof.
 *
 * Pass `callbacks = []` for standard (non-callback) workflows.
