Build: migrate to uv-managed environment

Convert project to modern uv-based package management:
- Consolidate requirements*.txt into pyproject.toml dependencies
- Migrate setup.cfg and mypy.ini to pyproject.toml tool sections
- Generate uv.lock for reproducible builds (303 packages resolved)
- Add UV_USAGE.md documentation for developers
- Configure Hatchling build system
- Set Python 3.11+ as minimum version
- Update REUSE.toml to annotate uv.lock
- Exclude uv.lock from large file checks in pre-commit

This enables modern Python development workflow with faster
dependency resolution and reproducible environments.

+# Development with uv
+
+This project now uses [uv](https://docs.astral.sh/uv/) for Python package and environment management.
+
+## Setup
+
+### Install uv
+
+Follow the [official installation guide](https://docs.astral.sh/uv/getting-started/installation/):
+
+```bash
+# On macOS and Linux
+curl -LsSf https://astral.sh/uv/install.sh | sh
+
+# On Windows
+powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
+```
+
+### Create and activate environment
+
+```bash
+# Create virtual environment and install dependencies
+uv sync
+
+# Activate the environment (optional, uv run handles this automatically)
+source .venv/bin/activate  # On macOS/Linux
+.venv\Scripts\activate     # On Windows
+```
+
+## Usage
+
+### Running commands
+
+Use `uv run` to execute commands within the project environment:
+
+```bash
+# Run Python
+uv run python -c "import custom_components.rental_control"
+
+# Run pytest
+uv run pytest
+
+# Run pytest with coverage
+uv run pytest --cov=custom_components.rental_control
+
+# Run any Python script
+uv run python my_script.py
+```
+
+### Managing dependencies
+
+```bash
+# Add a dependency
+uv add package-name
+
+# Add a dev dependency
+uv add --group dev package-name
+
+# Add a test dependency
+uv add --optional test package-name
+
+# Update dependencies
+uv sync
+
+# Update a specific package
+uv lock --upgrade-package package-name
+```
+
+### Testing
+
+```bash
+# Run all tests
+uv run pytest
+
+# Run specific test file
+uv run pytest tests/test_file.py
+
+# Run with coverage
+uv run pytest --cov=custom_components.rental_control
+
+# Run with verbose output
+uv run pytest -v
+```
+
+## Migration from requirements.txt
+
+The project has been migrated from the traditional `requirements*.txt` and `setup.cfg` format to `pyproject.toml`. The old files are preserved for reference but are no longer used:
+
+- `requirements.txt` → `[project.dependencies]` in `pyproject.toml`
+- `requirements_dev.txt` → `[dependency-groups.dev]` in `pyproject.toml`
+- `requirements_test.txt` → `[project.optional-dependencies.test]` in `pyproject.toml`
+- `setup.cfg` → Various `[tool.*]` sections in `pyproject.toml`
+- `mypy.ini` → `[tool.mypy]` in `pyproject.toml`
+
+## Benefits of uv
+
+- **Fast**: 10-100x faster than pip
+- **Reliable**: Reproducible builds with uv.lock
+- **Simple**: Single tool for package and environment management
+- **Compatible**: Works with existing Python tools and workflows
+
+## CI/CD Integration
+
+For GitHub Actions:
+
+```yaml
+- name: Install uv
+  uses: astral-sh/setup-uv@v5
+
+- name: Install dependencies
+  run: uv sync
+
+- name: Run tests
+  run: uv run pytest
+```
