feat: introduce partial clone for git

- ...or more specifically, blobless clone.
- For more details, see https://github.blog/2020-12-21-get-up-to-speed-with-partial-clone-and-shallow-clone/
- GitHub, or Microsoft's Developer Division (as the time of that blog post), has far more experiences on monorepo than me :-)
- TL;DR: "These clones download all reachable commits and trees while fetching blobs on-demand. These clones are best for developers and build environments that span multiple builds."
- Also use blobless clone for bootstrap, since after all we'll fetch without depth parameter, shallow clone the abbs tree provides no advantage. See blog post above for more details on this.
- Bump version to 20240124.
