Remove outdated async documentation from GNMIClient module:
- Remove async context manager from feature list
- Remove async usage example from class docstring
The client now only documents synchronous usage patterns.
Improve table readability by aligning columns with consistent
spacing and proper markdown table formatting throughout the
YANG paths reference documentation.
- Replace placeholder deps with click, pygnmi, and rich for CLI functionality
- Add fabric-orch CLI entry point via project.scripts
- Configure hatchling as build backend with wheel/sdist targets
- Add ruff linter configuration for code quality
- Add dev dependency group with ruff
- Alphabetize yang module imports
The `Optional` type was imported from `typing` in `src/yang/paths.py`
but was not being used in the file. This change removes the unnecessary
import to clean up the code.
- Update the dependency installation command in the main README to use `uv sync` instead of `pip`, reflecting the project's package manager.
- Realign markdown tables in `src/yang/README.md` to improve raw text readability and consistency.
