Motivation

• Provide per-request query parameters and timeouts and allow configuring default HTTParty options for clients.
• Make it possible to pass other HTTParty request options and control precedence between defaults, per-request options:, and explicit arguments.

Description

• Added default_options class setter and extended get, post, put, and delete signatures to accept query:, timeout:, and options: (and body: for delete).
• Reworked request to accept the new keywords and introduced build_request_options to merge @default_options, per-request options, and explicit arguments with the intended precedence and without mutating input hashes.
• Updated build_headers logic and header merging so headers from defaults, generic options[:headers], and explicit headers: are merged with explicit request headers taking precedence.
• Updated README.md with usage examples for query:, timeout:, options:, default_options, and the modified method signatures.
• Added spec/service_client_options_spec.rb with RSpec tests that validate option merging, header merging, immutability of option hashes, omission of unset optional values, body/query passthrough, and ParamsRequired behavior.

Testing

• Added an RSpec file spec/service_client_options_spec.rb that exercises merging precedence, header merging, immutability, omission of unset values, and parameter passthrough.
• Ran the RSpec suite covering the new specs and the new tests passed.
• Verified that HTTParty is called with the expected merged option hashes in the tests.
