v1.0.1 — Migrate to uv + ruff

What's changed

Tooling

• uv replaces requirements.txt as the package manager; install with uv sync
• ruff added as a dev dependency for linting and formatting
• Python pinned to 3.12 via .python-version

Dependency change

• Switched python-escpos[all] → python-escpos[usb] — drops the pycups build dependency that required system CUPS headers (the project only uses USB printing)

Code quality

• Fixed 30 ruff violations across the codebase: import ordering, unused imports, deprecated typing aliases, mutable/callable default arguments, and module-level import placement

Documentation

• README rewritten with proper markdown structure, photo comparison table, and complete install / configuration / run / development instructions
