Convert HTTParty to Faraday for HTTP client standardization

[Copilot]

Replaced all HTTParty usage with Faraday to standardize the HTTP client library across the codebase.

Changes

• Dependencies: Replaced httparty with faraday in spectrum-config.gemspec and spectrum-json.gemspec
• HTTP calls: Converted 4 HTTParty calls to Faraday equivalents:
  • engine.rb: Primo search API call
  • lib_key.rb: LibKey API call with custom headers and 0.5s timeout
  • Rakefile: GitHub releases API and CMS staff API calls
• Error handling: Added JSON::ParserError and Faraday::Error exception handling for all converted calls
• Requires: Added explicit require "json" statements in config.rb and Rakefile

API mapping

# Before (HTTParty)
response = HTTParty.get(url)
data = response.parsed_response
status = response.code

# After (Faraday)
response = Faraday.get(url)
data = JSON.parse(response.body)
status = response.status

# With timeout (HTTParty)
HTTParty.get(url, headers: headers, open_timeout: 0.5)

# With timeout (Faraday)
conn = Faraday.new { |f| f.options.open_timeout = 0.5 }
conn.get(url, {}, headers)

All existing tests pass. Faraday was already present as a transitive dependency through alma_rest_client.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• s3.amazonaws.com
  • Triggering command: /usr/bin/ruby3.2 /usr/bin/ruby3.2 -I/usr/lib/ruby/vendor_ruby extconf.rb --gdwarf-5 --64 -o escape.o /tmp/cclXPxzP.s -Wdate-time y-3.2.0 -g -gcc -I by-3.2.0 86_64-linux-gnu//usr/include/ruby-3.2.0 kward uby-3.2.0 /usr/include/rub-I -I E=3 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
