v0.2.0 - Memory graph visualization

v0.2.0 - Memory graph visualization

Memnex v0.2.0 publishes only the memory system layer and adds a local graph
viewer for inspecting memory graph structure without committing private memory
data.

What is included

• A local 2D/3D memory graph viewer exporter under
  memory-system/tools/graph-viewer/.
• Static browser assets for Cytoscape.js 2D graph exploration and
  3d-force-graph 3D exploration.
• Read-only SQLite export from graph tables into graph.json.
• README and memory-system documentation for the visualization workflow.
• Git ignore rules that exclude live memory data, generated graph viewer output,
  SQLite databases, WAL/SHM files, logs, and temporary files.

Privacy boundary

This release intentionally excludes memory-data/ from Git. It contains system
files only: documentation, scripts, viewer source, and static assets. It does
not include live memory exports, raw memories, database snapshots, logs,
transcripts, backups, or generated graph exports.

How to use

python .\memory-system\tools\graph-viewer\export_graph_viewer.py `
  --db "$env:USERPROFILE\.tam\memory.db" `
  --output .\graph-viewer-output

Open graph-viewer-output\index.html for 2D mode or
graph-viewer-output\viewer-3d.html for 3D mode.

Current limitations

• The graph viewer is a local static export, not a hosted service.
• Generated graph.json can contain private memory summaries; keep exported
  viewer directories private unless reviewed.
• The exporter expects Total Agent Memory-style graph tables.
