Summary

This release adds a dependency graph visualizer and an interactive graph editor.
The new tooling makes it possible to inspect a ModelMapping, see which models
produce and consume each variable, diagnose missing initialization values, and
interactively build or revise a mapping from a browser UI.

The static graph viewer is available directly from PlantSimEngine through
write_graph_view, graph_view, and graph_view_json. The live editor is
provided by the PlantSimEngineGraphEditorExt package extension and is loaded
when HTTP.jl is available in the session. The release also includes benchmark
and CI maintenance, updated developer guidance, and a new agent skill for
working with PlantSimEngine internals.

Added

• New dependency graph visualization API:
  graph_view, graph_view_json, compile_graph_view, and
  write_graph_view.
• A standalone HTML graph viewer with model nodes, variable ports, hard-call
  edges, variable dependency edges, scale filters, relationship filters, search,
  overview/detail modes, and an inspector.
• An interactive browser-based graph editor through edit_graph, backed by a
  local HTTP.jl server and WebSocket session.
• The live graph editor runs as a package extension that depends on
  HTTP.jl; static graph visualization is available without loading
  HTTP.
• Editing support for adding, updating, removing, and reconnecting models in a
  ModelMapping.
• Support for starting the editor from a blank mapping with edit_graph().
• Mapping-code generation from the editor, including using PackageName
  statements for loaded model packages and a top-level mapping variable.
• Save, autosave, recent-file reopening, undo, and redo support in live graph
  editing sessions.
• Model discovery helpers:
  available_processes, available_models, model_descriptor, and
  model_constructor_descriptor.
• Editor suggestions for adding producer models from input variables and
  consumer models from output variables.
• Cycle diagnostics in the graph UI, including highlighted cycle edges and an
  interactive way to wrap selected inputs in PreviousTimeStep.
• Visualization of required initialization values and graph diagnostics even
  when a mapping is incomplete or cyclic.
• A new documentation page for graph visualization and editing:
  docs/src/step_by_step/graph_visualization_editor.md.
• Playwright end-to-end tests for the browser editor and new Julia tests for
  the static graph viewer and editor extension.
• A local plantsimengine Codex skill describing the package architecture and
  contributor workflow.

Fixed

• Fixed type promotion behavior with ModelMapping.
• Fixed benchmark and documentation issues that were blocking CI.
