chore: switch CI to uv, remove uv.lock from gitignore (#885)

* chore: declare pytest as a uv dev dependency

The contributing guide currently tells contributors `pip install pytest`
as a separate step, and CI does the same. Move pytest into PEP 735
`[dependency-groups]` so it's declared in pyproject.toml and `uv sync`
installs it by default (no `--with` workaround, no separate install
line). Update CI to use astral-sh/setup-uv + `uv sync` + `uv run pytest`,
and refresh the Contributing section of the README to match.

`[dependency-groups]` is the right home (vs `[project.optional-dependencies]`)
because pytest is dev-only and shouldn't appear in the published wheel's
optional features list alongside things like `pdf` or `mcp`.

 ### Development setup
 
-Clone the repo and install in editable mode:
+The project uses [uv](https://docs.astral.sh/uv/) for dev workflow. Install it once, then:
 
 ```bash
 git clone https://github.com/safishamsi/graphify.git
 cd graphify
 git checkout v8                        # active development branch
 
-# Create a virtual environment (Python 3.10+ required):
-python3 -m venv .venv
-source .venv/bin/activate              # Windows: .venv\Scripts\activate
-
-# Install in editable mode with all optional extras:
-pip install -e ".[all]"
+# Create the project venv and install graphify + all extras + the dev group
+# (pytest). uv installs the dev dependency group by default; pass --no-dev to
+# skip it.
+uv sync --all-extras
 ```
 
 Verify the editable install:
 ```bash
-graphify --version
-python -c "import graphify; print(graphify.__file__)"
+uv run graphify --version
+uv run python -c "import graphify; print(graphify.__file__)"
 ```
 
 ### Running tests
 
 ```bash
-pip install pytest
-pytest tests/ -q                       # run the full suite
-pytest tests/test_extract.py -q        # one module

+uv run pytest tests/test_extract.py -q # one module
+uv run pytest tests/ -q -k "python"    # filter by name
 ```
