Migrate to Centralized NuGet Package Management (CPM)

[Copilot]

• Explore repo and collect all package references with versions
• Create Directory.Packages.props at repo root with all unique packages (sorted alphabetically)
• Remove Version="..." from all <PackageReference> elements in the 3 .csproj files
• Add Directory.Packages.props to the Misc Solution Items folder in Gress.sln
• Fix formatting in Directory.Packages.props to match Directory.Build.props style (blank lines after <Project>, between groups, and before </Project>)
• Collapse multi-line Avalonia.Diagnostics PackageReference to single line now that Version attribute is removed
• Build to verify changes are correct (all projects build successfully)

Original prompt

Migrate to Centralized NuGet Package Management (CPM)

Migrate the repository from per-project Version attributes on <PackageReference> to NuGet's Centralized Package Management (CPM).

What to do

1. Create a Directory.Packages.props file at the root of the repository with <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally> and a <PackageVersion> entry for every unique package used across all .csproj files. Use the version already present in the .csproj files.

2. Update all .csproj files to remove the Version="..." attribute from every <PackageReference> element (CPM now manages the version centrally). Keep all other attributes (e.g. PrivateAssets, Condition, ExcludeAssets, etc.) intact.

3. Add Directory.Packages.props to the .sln file as a solution item, typically under a Solution Items folder, so it is visible and accessible from within the solution.

4. Do not change any TargetFramework(s), project structure, or anything unrelated to package versioning.

See how it was done in the sibling repo Tyrrrz/YoutubeExplode PR #940: Tyrrrz/YoutubeExplode#940

Notes

• If a package appears with different versions in different projects, use the highest version and make a note in the PR description.
• <PackageVersion> entries in Directory.Packages.props should be sorted alphabetically.
• Make sure the file includes a valid MSBuild props file <Project> root element.
• Preserve all Condition attributes on <PackageReference> elements.

Pull request overview

This pull request migrates the Gress repository to use NuGet's Centralized Package Management (CPM), consolidating all package version definitions from individual .csproj files into a single Directory.Packages.props file at the repository root. This enables centralized version management across all projects in the solution, improving maintainability and consistency.

Changes:

• Created Directory.Packages.props with all 15 package versions defined centrally and sorted alphabetically
• Removed Version attributes from all <PackageReference> elements in project files while preserving other attributes
• Added Directory.Packages.props to the solution's Misc folder for visibility

Fixed in 6bbbbf2 — added blank lines after <Project>, between <PropertyGroup> and <ItemGroup>, and before </Project> to match the style in Directory.Build.props.

Fixed in 1302ea4 — collapsed the multi-line Avalonia.Diagnostics PackageReference to a single line now that Version is no longer needed as a separate attribute.
