  1. Prefer TOML-native config over legacy_tox_ini in pyproject.toml (#3776) 

    Swap the discovery priority of TomlPyProject and LegacyToml so that
native TOML configuration ([tool.tox]) is preferred over legacy_tox_ini
when both are present in pyproject.toml. This allows users to include a
legacy_tox_ini section with min_version for backward compatibility with
older tox versions while using native TOML config for newer ones.

Fixes #3402

  2. ✨ feat(config): add package = "deps-only" mode (#3774) 

    Many tox environments -- coverage combining, doc building, linting --
need a project's dependencies (and extras) but not the project itself.
Today the only option is `skip_install = true` plus manually duplicating
every dependency in `deps`, which drifts out of sync with
`pyproject.toml`. This adds `package = "deps-only"` so those
environments can declare `extras = ["docs"]` and get the right
dependencies automatically, just like a normal test environment, without
paying for a build step. 🎯

The implementation uses a two-tier resolution strategy. It first tries
to read dependencies statically from a PEP 621 `[project]` table in
`pyproject.toml` -- no packaging environment needed, same fast path as
`dependency_groups`. If that fails (dynamic deps, no `[project]` table,
`setup.cfg`-only projects), it falls back to the existing `.pkg` env and
`prepare_metadata_for_build_wheel` to extract metadata. A new
`load_deps_for_env` abstract method on `PythonPackageToxEnv` exposes
this fallback cleanly to the runner.

The `extras` config key works identically to other package modes,
including validation of unknown extra names. Existing configurations are
unaffected -- `deps-only` is purely opt-in alongside the existing
`wheel`, `sdist`, `sdist-wheel`, `editable`, `editable-legacy`, `skip`,
and `external` modes.

Fixes #2301
