build: migrate from poetry to uv

[mpf82]

Changelog: build

Closes: #2

[Copilot]

Pull request overview

Migrates the project’s packaging/build workflow from Poetry to uv by updating pyproject.toml to use the uv_build backend, removing the Poetry lockfile, and reorganizing tooling configuration (notably Ruff) into dedicated config files.

Changes:

• Switch build backend from poetry-core to uv_build and refresh dependency group definitions.
• Add standalone ruff.toml and remove Ruff configuration from pyproject.toml.
• Remove poetry.lock and expand .gitignore for common build/venv/coverage artifacts.
