Add a ref-counted decoded bytecode cache backing so bytecode cache materialization can create fresh script or module records from a shared decoded sidecar without passing around one-shot raw blob ownership. Keep that backing in ExecutableBacking for records materialized from bytecode cache sidecars, so the immutable decoded data stays alive for as long as the installed record needs it. Cover the shared backing path with a bytecode-cache test that materializes and runs two scripts from one decoded backing.
