add synchronization package, improve handling of optional features

[georghinkel]

Summary by MergeMonkey

• New Features:
  • Added synchronization package with supporting NuGet spec and binaries
  • Introduced CalculateStartOffset, CalculateEndOffset, and CreateEdit helper methods in Parser to centralize TextEdit creation
• Bug Fixes:
  • Fixed token handling in ParseObject to return true only when a model token exists
  • Added null guard in LspTypesMapper.MapWorkspaceEdit for safe handling of null changes
  • Improved CollectionChangeListener by filtering items with OfType to prevent invalid casts
• Chores:
  • Updated solution file version and added new package files to project list
  • Adjusted package tags and dependencies in nuspec files

Walkthrough

The PR introduces a new synchronization package and refactors the parser to use dedicated helper methods for offset calculations and edit creation, improving readability and maintainability. It also adds defensive null checks and type filtering to enhance robustness across LSP mapping and collection change tracking. Metadata, tags, and history logs are updated to reflect the new functionality.

Changes (File-by-file breakdown)

File	Changes
AnyText/AnyText.Core/Parser.cs	Extracted offset computation into CalculateStartOffset and CalculateEndOffset, and added CreateEdit to centralize TextEdit generation, simplifying the edit creation flow
AnyText/NMF-Anytext-Sync.nuspec	Created new NuGet package definition for AnyText synchronization, including metadata, dependencies, and file entries for binaries and documentation
AnyText/AnyText.Core/Model/ParseObject.cs	Modified TryPeekModelToken and TryConsumeModelToken to return true only when modelToken is not null, fixing null‑token handling
AnyText/AnyText.Generator/Transformation/AnytextCodeGenerator.cs	Performed minor cleanup in code generation method without altering functionality
AnyText/AnyText.Lsp/LspTypesMapper.cs	Added null check for changes parameter in MapWorkspaceEdit to safely return null when no changes are provided
AnyText/AnyText.history	Updated history entries to record addition of synchronization package and minor transaction synchronization changes
AnyText/NMF-Anytext-LSP.nuspec	Changed package tags from GLSP to LSP to reflect correct technology focus
AnyText/NMF-Anytext.nuspec	Removed GLSP tag from package metadata
Expressions/Expressions.history	Added history entries for improved FirstOrDefault and a fix for cast exceptions when handling non‑model collections
Expressions/Expressions/Execution/CollectionChangeListener.cs	Imported System.Linq and filtered moved, replacing, and removed items using OfType<T> to prevent invalid casts
NMF.sln	Removed VisualStudioVersion suffix and added synchronization package files to solution project list
