Only read FOUNDRY_WINDOWS_AI_MACHINELEARNING_VERSION when --winml is enabled so a globally-set environment variable does not break standard installs.

- Python: prefer exact filename matches in _find_file_in_package and rename the WinML runtime temp file so a leftover .tmp (from an interrupted install) cannot be mistaken for the real DLL by the fuzzy *filename* glob; mark the success path explicitly so the temp cleanup only runs on failure.

- C++: skip DirectML.dll during the WinML copy loop instead of copying it and then removing it post-build.

- Drop always_extract: true on Microsoft.ML.OnnxRuntime.Foundry in the WinML build path. The WinML runtime NuGet (always_extract: true) still re-extracts every build to keep packages_require_extraction true and overwrite any stale runtime DLL; ORT itself doesn't need to redownload on every build.

- Make DirectML.dll cleanup best-effort with a cargo warning instead of expect()/panic, so a locked DLL (common on Windows when a prior process still holds a handle) doesn't fail the entire build script.

- samples/README.md: correct C# sample count (13, not 14).

- Revert C# catalog ordering change (preserve-Core-order) and its test. The change is preserved on branch bhamehta/cs-catalog-preserve-order for a future PR.

- sdk/deps_versions_winml.json: revert foundry-local-core nuget/python versions back to 1.1.0 since they are overridden in CI.

- Rename FOUNDRY_WINDOWS_AI_MACHINELEARNING_VERSION to FOUNDRY_LOCAL_WINDOWS_AI_MACHINELEARNING_VERSION for consistency with the FOUNDRY_LOCAL_ prefix convention. Updates all SDKs (Python, Rust, JS, C++ CMake) and their READMEs.

Per offline guidance, the C++ SDK will be replaced shortly, so this PR no longer changes any sdk/cpp/* files. Revert all sdk/cpp/* edits to match origin/main, drop the WinML-specific CMake module, and remove the C++ verify-winml sample (which depended on those SDK changes via add_subdirectory). The pre-existing samples/cpp/live-audio-transcription sample is untouched, and the C++ row in samples/README.md is removed since this PR no longer contributes new C++ samples.

Five files revert to origin/main since their changes are not required by the WinML 2.0 preview samples work:

- sdk/js/native/foundry_local_napi.c: the optional execute_command_with_binary fix targeted Microsoft.AI.Foundry.Local.Core.WinML 1.0.0 (which omitted the symbol). The PR now pins to 1.1.0, which exports it, so the fix is dead code. The accompanying ~225-line refactor is unrelated cleanup.

- sdk/js/test/foundryLocalManager.test.ts, sdk/js/test/model.test.ts: hoist getTestManager() into before hooks, raise the suite timeout, and add skip-if-cached-models-missing logic. General test hygiene, unrelated to WinML 2.0.

- samples/js/copilot-sdk-foundry-local/src/app.ts: comment wording change in a sample that does not use WinML.

- samples/cs/Directory.Packages.props: restore Betalgo.Ranul.OpenAI 9.2.0. Verified locally that 9.2.0 restores cleanly on net9.0-windows10.0.18362.0; the earlier downgrade was incidental.

samples/cpp/live-audio-transcription already exists on main but is missing from the per-language sample table. Add a one-line row so the table is consistent with the other languages.

DownloadProgressCallback has been std::function<bool(float percentage)> since PR #683 (Cross Platform C++ SDK), but the lambda example in the README still doesn't return a value, so the example fails to compile. Add an explicit return true to follow the cancellation API contract (return true to continue, false to cancel).
