v4.0.0

sumt 4.0.0

This is a major release with CLI-breaking changes and several new features.

Highlights

• Removed per-file input flags and weights: input files are now positional (sumt [OPTIONS] FILE [FILE ...]), and file weighting (-w, --autow) has been removed (each tree counts equally).
• Added credible intervals for branch lengths / node depths: --ci PROB[,PROB,...] (e.g. --ci 0.8,0.95).
• Added multiprocessing for faster processing on large tree sets: --cpus N and --chunksize N.
• Simplified output formats: --outformat {newick,nexus}; use --nometa to omit metacomment annotations.
