Add compact option to attributes and serialize_structured_value methods

[Syati]

This pull request enhances the StructuredParams::Params class by introducing a new compact option to the attributes and serialize_structured_value methods, allowing for recursive removal of nil values from structured parameter hashes. The changes also update type signatures and add comprehensive tests to ensure correct behavior.

Feature addition: Compact attributes

• Added a compact keyword argument to the attributes and serialize_structured_value methods in lib/structured_params/params.rb, enabling recursive removal of nil values from returned hashes. [1] [2]

Type signature updates

• Updated the attributes and serialize_structured_value method signatures in sig/structured_params/params.rbs to reflect the new compact argument and its accepted combinations. [1] [2]

Test coverage

• Modified and extended tests in spec/params_spec.rb to cover the new compact option, including cases with nested hashes, arrays, and symbolized keys, verifying that nil values are removed as expected. [1] [2]
