Replace all access of `@attributes` and `attributes` key-value pairs with calls to `read_attribute` and `write_attribute`. The `read_attribute` and `write_attribute` implementations draw inspiration from [ActiveRecord::AttributeMethods::Read][] and [ActiveRecord::AttributeMethods::Write][], respectively. [rails/rails#53886][] proposes implementing each method at the Active Model layer. While that proposal is considered, this commit implements each method in terms of accessing the underlying `@attributes` hash instance. This change is also in support of a first-party integration with [ActiveModel::Attributes][] proposed in [rails#410][], and aims to be compatible with its attribute reading and writing interfaces. ```ruby person = Person.find(1) person.read_attribute("name") # => "Matz" person.name # => "Matz" person.write_attribute("name", "matz") person.name # => "matz" ``` [ActiveRecord::AttributeMethods::Read]: https://edgeapi.rubyonrails.org/classes/ActiveRecord/AttributeMethods/Read.html#method-i-read_attribute [ActiveRecord::AttributeMethods::Write]: https://edgeapi.rubyonrails.org/classes/ActiveRecord/AttributeMethods/Write.html#method-i-write_attribute [rails/rails#53886]: rails/rails#53886 [ActiveModel::Attributes]: https://edgeapi.rubyonrails.org/classes/ActiveModel/Attributes.html [rails#410]: rails#410
