GISPulse v2.2.0

[2.2.0]

Feature release adding a coherent set of generic GIS capabilities for
network analysis, linear referencing and clustering (the "A–K" plan), plus a
unified multi-source data provider. Fully backwards-compatible.

Added

• Unified data loader & providers (#374). gispulse.load(source, …) /
  app.load() resolve files (incl. GeoParquet), remote URIs (s3/http),
  wfs:// / stac:// / ogc-features://, datamarts (datamart://, curated
  Parquet) and GeoNode instances (geonode://, read + publish() write) to a
  GeoDataFrame or a lazy DuckDB scan.
• SpatialIndex (K) & NetworkGraph (F). Reusable core infrastructure: a
  thin STRtree wrapper (build once / query many) and a persistent routing
  handle that builds the NetworkX graph once and snaps points to nodes in
  O(log n). All network capabilities (shortest_path, isochrone,
  od_matrix, mst, network_allocation, connectivity_check) now reuse the
  handle instead of rebuilding the graph and scanning nodes linearly.
• build_network_graph (A). Turns a line layer into a tagged node/edge
  GeoDataFrame with stable ids, degrees and metric lengths.
• snap_points_to_lines (B) and split_lines_at_points (C). Snap a
  point layer onto a line network; cut lines at a reference point layer.
• planarize (D) and connected_components (E). Attribute-preserving
  planar noding; label network islands.
• steiner_tree (G). Approximate minimum Steiner tree connecting a subset
  of terminal points at near-minimum total cost.
• cluster_network_dbscan (H). DBSCAN using shortest-path distance along a
  network instead of straight-line distance.
• community_detection (I). Partition a network into communities (Louvain
  / greedy modularity / label propagation); tags each edge with a
  community_id.
• cluster_st_dbscan (J). Spatio-temporal DBSCAN combining a spatial
  (eps_m) and a temporal (eps_time) threshold.
