(Migrated from github.com)

Parent: #2
Depends on: #7, #8, #12

Scope

Wrap Cytoscape.js behind a typed GraphAdapter.
Support full snapshot load, incremental add/update/remove, positions, selection, fit, viewport export, stylesheet updates, and layouts.
Centralize extension registration and version compatibility tests.
Begin with selected layouts and edge creation support; add extensions individually rather than wholesale.
Keep pointer movement, drag frames, zoom frames, hover, and layout animation browser-local.

Acceptance criteria

No package outside src/graph accesses the Cytoscape instance.
Adapter events are committed semantic events, not high-frequency raw frames.
Snapshot and incremental projection produce equivalent visible state.
Renderer teardown removes listeners and resources.
Compatibility tests cover every enabled extension.
