PanBreak 0.1.1

Added

• panbreak check: reports the Python dependencies and external tools that PanBreak can find, with
  versions and the subcommands that need them.
• End-to-end test on a toy graph and an unaligned BAM (bubbles → kmers → genotype), run in CI
  and in the conda package test.
• CI job that installs the conda environment on Linux and macOS (arm64) and builds the conda package
  from the repository.

Changed

• GFF files with GTF-style attributes (key "value", e.g. liftoff output) are accepted by
  regions and annotate.
• Insertion clustering across genomes; bubble labels prefer protein-coding genes.
• Graph layout and haplotype flow plots scale to large panels.
• Python 3.10 or newer is required; tested with 3.10, 3.12 and 3.13.
• Package metadata uses an SPDX license expression.

Install from source with conda env create -f environment.yml (see the README). panbreak check lists the tools PanBreak finds.
