This splits the pure content-addressed layers from tvix-store into a `castore` crate, and only leaves PathInfo related things, as well as the CLI entrypoint in the tvix-store crate. Notable changes: - `fixtures` and `utils` had to be moved out of the `test` cfg, so they can be imported from tvix-store. - Some ad-hoc fixtures in the test were moved to proper fixtures in the same step. - The protos are now created by a (more static) recipe in the protos/ directory. The (now two) golang targets are commented out, as it's not possible to update them properly in the same CL. This will be done by a followup CL once this is merged (and whitby deployed) Bug: https://b.tvl.fyi/issues/301 Change-Id: I8d675d4bf1fb697eb7d479747c1b1e3635718107 Reviewed-on: https://cl.tvl.fyi/c/depot/+/9370 Reviewed-by: tazjin <tazjin@tvl.su> Reviewed-by: flokli <flokli@flokli.de> Autosubmit: flokli <flokli@flokli.de> Tested-by: BuildkiteCI Reviewed-by: Connor Brewster <cbrewster@hey.com>
