v0.8.5: The Query Engine Update (ORDER BY, Pagination, Layouts)

This release marks a major milestone for graph_kit, introducing a full suite of Cypher-like query capabilities, layout algorithms, and advanced filtering.

New Query Features
Sorting & Pagination: Added ORDER BY, SKIP, and LIMIT clauses (v0.8.5).
RETURN Clause: Project specific variables, properties, and aliases (e.g., RETURN person.name AS name) (v0.7.4).

Advanced Filtering:
CONTAINS operator for substring matching (v0.7.7).
Inline property filters (e.g., node:User{active:true}) (v0.8.2).
Edge variable comparisons in WHERE (v0.8.1).
Flexible Starting Points: Support for multiple startIds and starting from middle elements in a pattern (v0.8.0, v0.7.5).
Layout & Visualization
GraphLayout API: Automatic layer and column computation for visualizing graphs, handling cycles and disconnected components (v0.7.6).

Core Improvements
Relationship Properties: Full support for persisting and querying properties on edges (v0.8.3).
Variable-Length Paths: Improved metadata support and path reconstruction for variable-length segments (v0.8.4, v0.7.9).

RETURN Clause Support - Clean Query Results with Property Projection

Release Notes:

RETURN Clause Support

This release adds complete RETURN clause support, allowing you to project specific variables and properties from your query results for cleaner, more usable data.

Features

Variable Projection

RETURN person, team  // Returns node IDs

Property Access
RETURN person.name, person.salary, team.size  // Direct property access

AS Aliasing
RETURN person.name AS employee, person.salary AS pay

Dart 3 Destructuring
final results = query.matchRows(
  'MATCH person:Person WHERE person.salary > 90000 '
  'RETURN person.name AS name, person.salary AS salary'
);

for (var {'name': empName, 'salary': pay} in results) {
  print('$empName earns \$$pay');
}
