Release 0.11.0 on the released IOScene 0.1.0, so that the tag v0.11.0 publishes IfcIO, IfcIO.Cli and, for the first time, IfcIO.Scene.

What changes

• Directory.Packages.props: IOScene [0.1.0-preview.2, 0.2.0-0) becomes [0.1.0, 0.2.0-0). IOScene 0.1.0 is on nuget.org; the pack-release.ps1 check that refuses a preview lower bound now passes.
• Directory.Build.props: version 0.11.0.
• CHANGELOG.md: ## [0.11.0] - 2026-11-13 with the entries that were under [Unreleased] (the IfcIO.Scene adapter and package, the world placement fix of fix: place IFC geometry in world coordinates and export GLB in metres, +Y up #35, the GLB units and axes, the frozen extras of docs: document frozen extras and their planned replacements #37), and an empty [Unreleased]. The package entry now names the range instead of saying it waits for IOScene 0.1.0.
• README.md: version 0.11.0 in Limitations; the frozen-extras section no longer calls IfcIO.Scene and IOScene planned, and says that none of the replacements is published yet (the follow-up noted in docs: document frozen extras and their planned replacements #37).
• docs/scene-adapter.md: the range [0.1.0, 0.2.0-0) instead of the preview range and the "a release fails on purpose" note.
• CONTRIBUTING.md: the range [0.1.0, 0.2.0-0). Restore takes the lowest version in the range, now 0.1.0 from nuget.org, so a local package folder alone no longer builds against an unpublished IOScene; the paragraph now says to start the range at that version first (and to move the upper bound for a new minor).

No source or API changes.

Checks

• dotnet restore, dotnet build IfcIO.slnx -c Release: 0 warnings, 0 errors; IOScene 0.1.0 restored from nuget.org with no other package source.
• dotnet test IfcIO.slnx -c Release: IfcIO.Tests 149 passed (net10.0); IfcIO.Scene.Tests 19 passed and 1 skipped (the test that needs a configured IFC file) on net8.0 and net10.0.
• tools/pack-release.ps1 (Windows PowerShell 5.1; the release job uses pwsh): exit 0. It builds the archives and IfcIO.0.11.0, IfcIO.Cli.0.11.0 and IfcIO.Scene.0.11.0; the IfcIO.Scene nuspec depends on IfcIO [0.11.0] and IOScene [0.1.0, 0.2.0-0) for net8.0 and net10.0, and both checks of the script pass.
• Not run: the release workflow itself (it runs only on the tag) and the docs build (it runs in CI on this PR).

Notes

• Found in review, not changed here: Directory.Build.props:38 turns on GenerateDocumentationFile only when IsPackable is true, but IsPackable is set later in src/IfcIO/IfcIO.csproj, so the IfcIO package has shipped without IfcIO.xml since the first release (IfcIO.Scene sets the property itself and has its XML file). Turning it on can raise new doc-comment warnings, which are errors here, so it is left for a later release.

After merge

Tag v0.11.0 on the merge commit. The CHANGELOG date is 2026-11-13; if the tag is pushed on a later day, the date should be corrected first.
