Update to v0.13.0

[networmix]

• Introduced unified node selection system.
• Enhanced variable and bracket expansion.
• Removed deprecated source_path and sink_path attributes.

---

Note

Introduce unified selector system (string or dict) replacing source_path/sink_path, add variable and bracket expansion across DSL, and update API/docs/tests accordingly.

• API/Core:
  • Replace source_path/sink_path with unified source/sink selectors (string regex or selector dict) across analysis (AnalysisContext, MaxFlow, sensitivity, helpers) and CLI.
  • Accept selectors in all workflows; add resolve_parallelism; adjust return/context data; remove ngraph.utils.nodes and move condition logic to dsl.selectors.
• DSL/Expansion:
  • Add ngraph.dsl.selectors (schema, normalization, condition evaluation) and use it for adjacency, demands, overrides, workflows.
  • Add ngraph.dsl.expansion (variable $var/${var} templates, zip/cartesian; name/bracket expansion) and enable bracket expansion in risk group definitions and memberships.
  • TrafficDemand gains source/sink, group_mode, expand_vars, expansion_mode; ID generation updated.
• Schema/Docs:
  • Update JSON schema (selectorOrString, match/group_by), README/examples, and extensive DSL reference/examples; add Claude skill docs.
• Scenarios/Tests:
  • Migrate scenarios and tests to new selectors; broaden test coverage for selectors/expansion/risk groups; remove legacy attr: directive usage.
• Versioning:
  • Bump version to 0.13.0; changelog updated.
