Describe the bug

There no longer appears to be a way to get pdm add to just edit pyproject.toml without performing a full resolution first.

To reproduce

Run pdm add --frozen-lockfile --no-sync some-file.

This will start a full resolver run (presumably to check locking is still possible) before modifying pyproject.toml, but I don't want pdm add to check that, I have a separate script for updating the lock file for all the required environments and exporting the relevant groups to flat requirements files as needed)

Expected Behavior

PDM edits pyproject.toml and does nothing else.
