The working directory of nodes with git fields is only decided on `dora build` because that's where we translate the branch/tag name into the commit hash.

Before, we fell back to using the base working directory if no build was done. However, this is confusing since the reason for the different working directory is not communicated in any.

This commit throws an error if no build happened before starting a dataflow with git nodes.

Most important change is https://github.com/GREsau/schemars/pull/310,
which keeps newlines unchanged during schema generation. This is
important to preserve the lists, markdown code blocks, and markdown
headings in our docs.

Note: This PR deliberately does not update the schema file yet in order
to test #1083. So it should be merged after #1083.

Also set `#![warn(missing_docs)]` for the module so that we get a
warning if we add undocumented fields etc in the future.

We forgot to create the working directory in a few cases in #901. This
PR fixes this by adding the proper `create_dir_all` calls.

Also includes a bit or regorganization to streamline the API.

Ensures that we see all error messages instead of just the exit code.

Parentheses in directory names confuse some build tools/scripts (e.g. openssl Makefile).

V7 UUIDs include a timestamp and are sortable. This is useful to see which ID is newer.

We don't want to include it for e.g. the `dora-node-api-c`.
