Replace the placeholder package description.

Line 40 adds Package Description without a description. The new #287 entry therefore has no summary. Populate the source metadata, if this README is generated, and regenerate this section with the actual package description.

Proposed fix 
- Package Description
+ Trims string properties in complex objects.

Use a pattern that exists in Program.cs.

The tour searches for this is the code, but v2/rscg_examples/TrimItEasy/src/TrimDemo/Program.cs contains FastTrimStrings. This step will not focus the editor on the sample code. Use a stable pattern such as FastTrimStrings.

v2/.tours/TrimItEasy.tour opens an untracked file under obj/GX. StartTourVSCode.Execute starts CodeTour without building or running TrimDemo.csproj. On a clean checkout without a prior compilation, the file may be missing when CodeTour opens it.

Correct the published description text consistently.

The description contains the typo eacg and the ungrammatical phrase from a class properties. Use clear wording such as Trim each string property in a class. in the source metadata, then update the generated documentation and video description copies.

Replace the placeholder package description.

nuget.txt contains only Package Description. The generated page renders this literal text in the Info section, so readers do not see what TrimItEasy does. Replace it with the actual package description. (raw.githubusercontent.com)
