fix(InlineModelResolver): do not merge untitled inline schemas differing only by description

[wing328]

based on #24007

PR checklist

• Read the contribution guidelines.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in WSL)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Summary by cubic

Limit structural-signature deduplication to titled schemas so anonymous inline schemas that differ only by description are no longer merged. This prevents accidental type collapsing and generates distinct models where appropriate.

• Bug Fixes
  • Updated InlineModelResolver.matchGenerated to apply structural-signature matching only to titled schemas; untitled inline schemas now remain distinct even if structurally identical after stripping volatile fields.
  • Regenerated samples to reflect distinct models and updated API signatures:
    • Crystal: added FilterMust, FilterMustNot, PrefetchPrefetch, TrackerStatusOneOf1; updated Filter.must/must_not, Prefetch.prefetch, and TrackerStatus to use them.
    • C#: introduced TestEnumParametersEnumHeaderStringParameter; used for both enum_header_string and enum_query_string, updated converters, FakeApi parameter types, docs, and tests across GenericHost samples.
    • Python (python-httpx, python-httpx-sync, python-aiohttp, python-lazyImports, python-pydantic-v1-aiohttp): added UploadFileWithAdditionalPropertiesRequestObject; updated FakeApi.upload_file_with_additional_properties to use it, refreshed docs, and updated tests (including a unit test for the model in python-httpx-sync).

^{Written for commit d1d9c98. Summary will update on new commits.}
