Subject: [PATCH] build(pyproject): declare `requires-python` via PEP 621
 `[project]` metadata

  Add a minimal `[project]` table to `pyproject.toml` and set:

  - `requires-python = ">=3.9"`
  - `name = "folium"`
  - `dynamic = [...]` for fields still sourced from `setup.py`

  Why this is needed:
  `python_requires` in `setup.py` is not enough for tools that read interpreter
  constraints from `pyproject.toml` metadata. Per PEP 621, `requires-python`
  belongs in `[project]`, which allows `uv` to resolve/lock against the correct
  Python range instead of defaulting incorrectly (see
  https://github.com/astral-sh/uv/issues/11424).
