Pull request overview

Syncs the dev branch into master for the 0.8.1 release, bringing in many new solvers/variants, rule-engine refactors (holes/grid_all, adjacency, shape helpers), and frontend import + rules-link improvements.

Changes:

• Add multiple new puzzle solvers and extend existing solvers to support new rule primitives (crossing routes, directed line handling, blue/water, etc.).
• Refactor core rule modules (common, neighbor, reachable, shape, variety) and propagate API changes across solvers.
• Update build/tooling (uv_build, ruff formatting/linting), bump PyScript, and enhance import UX in the frontend.
