LinuxHound 0.3.1

LinuxHound is now packaged for installation from PyPI, with the offline graph viewer and bundled Graph Neural Network (GNN) demo model.

python -m pip install linuxhound
linuxhound demo --open

For neural review ordering, install linuxhound[gnn] and run linuxhound demo --gnn --open. Live collection remains Linux only; the bundled model remains an uncalibrated synthetic demonstration.

This release adds package documentation links, README image links that work on PyPI, and GitHub trusted publishing restricted to release tags. Validation: 104 unit tests, JavaScript graph checks, strict distribution metadata checks and an isolated wheel-install demo.
