- Sigma.js graph: restore doc_type coloring (revert Louvain community detection)
- Fix animation flash after FA2 layout finishes by removing post-processing
camera reset and redundant noverlap/compactOrphans in stopLayout
- Fix vault tree "Load more" state bug when filtering by doc_type:
add treeVersion counter to force re-mount and reset auto-expand state
- Fix meta map loss: loadRoot now merges instead of replacing, preserving
subtree entries from previous loadSubtree calls
- Add compact graph DTO endpoints and hooks for KG and vault graphs
- Add semantic zoom tiers, adaptive FA2 settings, and node sizing
