Progress on #13405, which asks for an explicit characterisation of the
equivalence relation like the one given here.
Also progress on #11895, because we're using the term "build trace
entry" instead of "realisation".
Mention #9259, a future work item.

This continues the work for formalizing our current JSON docs. Note that
in the process, a few bugs were caught:
- `closureSize` was repeated twice, forgot `closureDownloadSize`
- `file*` fields should be `download*`. They are in fact called that in
the line-oriented `.narinfo` file, but were renamed in the JSON
format.
We immediately use this in the JSON schemas for Derivation and Deriving
Path, but we cannot yet use it in Store Object Info because those paths
*do* include the store dir currently.
See #13570 for details --- the idea is that included the store dir in
store paths makes systematic JSON parting with e.g. Serde, Aeson,
nlohmann, or similiar harder.
After talking to Eelco, we are changing the `Derivation` format right
away because not only is `nix derivation` technically experimental, we think it is
also less widely used in practice than, say, `nix path-info`.
Progress on #13570
Makes the behavoral change of #13263 without the underlying refactor.
Hopefully this clearly safe from a perf and GC perspective, and will
make it easier to benchmark #13263.
This is a big step documenting the store layer on its own, separately from the evaluator (and `builtins.derivation`).
