fix: remove unused Microsoft.CodeAnalysis dependencies (#157)

The library emits code via System.Reflection.Emit, not Roslyn, but a
global Microsoft.CodeAnalysis.CSharp.Scripting PackageReference in
Directory.Build.props pulled Microsoft.CodeAnalysis.CSharp (~6.6MB) and
Microsoft.CodeAnalysis.Common into every project, leaking them into
consumers' published output.

No CodeAnalysis/Roslyn API is used anywhere in the codebase, so remove
the references outright rather than masking them with PrivateAssets:

- Directory.Build.props: drop global CSharp.Scripting reference
- Hyperbee.Expressions: drop CodeAnalysis.Common / CodeAnalysis.CSharp
- Hyperbee.Expressions.Lab: drop CodeAnalysis.* plus other unused refs
  (Hyperbee.Collections, Extensions.Configuration[.Binder])
- Directory.Packages.props: drop orphaned CodeAnalysis version entries

Verified: full solution builds (net8/9/10, 0 warnings), all tests pass,
and the packed nuspec no longer declares any CodeAnalysis dependency.
