Fairly large update to existing code that bundles several QoL improvements and bugfixes
to improve user experience.

Bugfixes

• Fix NullPointerException raised when failing to resolve dependencies in certain cases
  (@​askoog, GH-980).
• Abstract away class references from Plexus parameter converters entirely. This avoids
  edge cases where ClassWorlds within Maven may try to classload the same classes in
  multiple places, causing class definition mismatches and breaking type conversion within
  POMs. This is a defensive workaround to the issue originally addressed by GH-974.
• Remove caching of sealed types to further avoid issues such as those in GH-974.
• Make configurator classes into singletons to enforce fixes for GH-974.

UX improvements

• Users are now warned in cases where we mitigate issues caused by overriding a string
  attribute in a child POM with an object attribute in a parent POM. The erroneous
  configuration is now logged as a warning, and a suggested fix is logged to the user.
• Improved error messages reported during failures in artifact resolution.

Performance improvements

• Optimise resolution logic for skipped plugins to remove unneeded forking of threads
  (@​cdprete, GH-975).
• Avoid creation of entire mappings of type information within SealedTypePlexusConverter
  during parameter conversion.
• URL transfers from FTP servers and HTTP/HTTPS endpoints now supports requesting GZIP
  compression of the response.

Internal improvements

• Fixes to documentation typos and grammar issues.
• Improvements to various unit tests, including addition of missing test cases.
• Improvements to code coverage and code quality.
• Internal package structure improvements.
• Build on macOS 26.
• Dependency updates.
