- MCP Server: 25 new commands for parity with nkarasiak/qgis-mcp v0.5.0
- Global CN: fixed swapped ARC I/II lookup tables, output path bug, dual hydrologic soil group handling, and mangrove CN value (issue #18, reported by @drkenny-git and @D-Trujillo32)

- MCP Server updated to 51 tools with backward compatibility for existing configurations

- Global CN: fix Bandit B310 security issue in URL fetch helper

- Added Multiple Basin Delineation tool (contribution by Anthropocene Engineering team - anthroeng.com)
- Enhanced Watershed Basin Delineation tool:
* Longest Flow Path calculation feature (suggested by Antonio López Espinazo)
* Topological network integration using r.drain
* Three Strahler order calculations (sthr_original, sthr_extend, sthr_final)
- Fixed topological issues in stream network merging
- Minor bug fixes and improvements

- Enhanced Image Classification: Advanced machine learning classification with Random Forest, SVM, GMM, and KNN algorithms, including scientific accuracy assessment and comprehensive HTML reports
- Least Cost Path Finder: Advanced path optimization with multiple optimization levels, flat terrain sensitivity, and support for drainage analysis, hiking trails, and utility corridors
- Tree Planting Pattern Generator: Generate optimal planting patterns (Triangular/Quincunx, Rectangular/Square, Five of Diamonds) for forestry and agricultural planning

1. Calculate Coordinates: Add XY coordinates to point layers, convert to Decimal Degrees, and provide two formats of Degrees Minutes Seconds.
2. Calculate Line Geometry: Calculate length and azimuth for line features.
3. Calculate Polygon Geometry: Calculate area and perimeter for polygon features.
4. Calculate Angles: Calculate internal and external angles at vertices of lines or polygons.
5. Go to XY: Quickly navigate to specific coordinates on the map and optionally create point markers.

6. Extract Ordered Points from Polygons: Extract and order points from the vertices of input polygons with bi-directional numbering.
7. Lines to Ordered Points: Convert line features to ordered point features.
8. Calculate Line from Coordinates and Table: Generate a line and points from starting coordinates and a table of distances and angles.

9. Stream Network with Order: Generate a stream network with Strahler order.
10. Multiple Basin Delineation: Delineate multiple basins from points, snap them to streams, and calculate drainage areas.
11. Watershed Basin Delineation: Delineate watershed basins from a DEM and pour points with main channel extension.
12. Watershed Morphometric Analysis: Perform a comprehensive morphometric analysis of a watershed, calculating various parameters and providing their interpretations.
13. Calculate Global Curve Number: Calculate CN values using global datasets for hydrological analysis.

14. Topographic Profile: Generate interactive topographic profiles from lines and DEMs with advanced visualization.
15. Least Cost Path Finder: Advanced path optimization for drainage channels, hiking trails, utility lines, and irrigation planning.

16. Land Use Change Detection: Analyze changes in land use between two time periods.
17. Weighted Sum Analysis: Perform weighted sum analysis on multiple raster layers.
18. Optimized Parcel Division: Divide parcels or blocks into lots by width or target area, optionally guided by street frontage lines.
19. Dam Flood Simulation: Simulate flooding based on a DEM and specified water level.

20. Enhanced Image Classification: Machine learning classification with scientific accuracy assessment.
21. Kriging Analysis: Perform spatial interpolation using Kriging (requires external libraries).
22. Satellite Index Calculator: Calculate various satellite indices (NDVI, NDWI, etc.) for different satellites.

23. Tree Planting Pattern Generator: Generate optimal tree planting patterns with comparative density analysis.

24. Basemap Manager: Add and manage basemaps from Google Maps, Esri, Bing, and others.
25. Screen Capture: Capture and georeference the current map view.
26. Export to CSV: Export vector layer attributes to CSV format compatible with Excel.
27. Export Contours to 3D CAD: Export contour lines to DXF format preserving elevation values.
