## changelog
- _semi\_avid_, _kzg_ and _aplonk_ examples have been added
- the `fs` module has been hidden behind an `fs` feature
- the `conversions` module has been properly hidden behind the `test` config feature
- the documentation has been completed
- some error messages have been improved

> **Note**
>
> the documentation of aPlonK has been left as-is for now

in dragoon/komodo!162 and dragoon/komodo!163, i did only run `cargo ... --all-features` without checking the individual features...

this MR adds some `cargo check --features ...` to the `Makefile` and makes sure the imports make sense when compiling a single feature.

>  **Important**
>
> the other notable change here is that `kzg::commit` has been moved to `zk::ark_commit` and is re-exported from `kzg` as `kzg::commit`.

this adds the KZG+ cryptographic method alongside Semi-AVID.

## changelog
- the Makefile now uses `--all-features` to compile everything
- a new module `algebra` has been added, with tests for all functions
  - `algebra::scalar_product_polynomial` computes a linear combination of polynomials $(P_i)$
  - `algebra::powers_of` computes $n$ successive powers of a number $r$
- a new function `zk::trim` has been added from [`gitlab.isae-supaero.fr:a.stevan/poly-commit@19fc0d4a/src/kzg10/mod.rs#L513-L538`](https://gitlab.isae-supaero.fr/a.stevan/poly-commit/-/blob/19fc0d4ad2bcff7df030c952d09649918dba7ddb/src/kzg10/mod.rs#L513-L538)
- a new feature `kzg` has been added, with an optional dependency on [`gitlab.isae-supaero.fr:a.stevan/poly-commit@19fc0d4a`](https://gitlab.isae-supaero.fr/a.stevan/poly-commit/-/tree/19fc0d4ad2bcff7df030c952d09649918dba7ddb)
- a new module `kzg` has been added and exposes the following publicly
  - structures
      - `Block`
  - functions
    - `commit`
    - `prove`
    - `verify`
    - `batch_verify`
  - tests when block are left as-is and when one of them is corrupted

## changelog
- `src/main.rs` has been moved to a new crate: `bins/saclin` which stands for **S**emi-**A**VID **CLI** in **N**ushell
- dependencies of `komodo` have been fixed
- Nushell and Rust tests have been split in the Makefile: by default, only Rust tests will run locally and Nushell tests and examples can be run manually if desired. The CI will still run everything.
- the README has been updated
- test images have been moved to `assets/`
- the majority of the old `./nu-utils/` module have been moved to internals of `./benchmarks/` and imports have been fixed
- `cargo.nu` has been moved to `./bins/` and a new `./bins/README.md` mentions it
- `./bins/saclin/` has been created and should be a self-contained Rust crate + Nushell module

this also bumps Nushell to 0.93.0 to include the "extra" command `fmt`, see [Nushell 0.92.0](https://www.nushell.sh/blog/2024-04-02-nushell_0_92_0.html#incorporating-the-extra-feature-by-default-toc)

this MR:
- refactors the "inbreeding" example into `examples/inbreeding/`
- adds `--strategy` and `--environment`
  - `Strategy::draw` will draw the number of shards to keep for recoding
  - `Environment::update` will update the pool of shards by losing some of them

- update `benches/README.md` to use `cargo run --release --example ...`
- add `build-examples` to `Makefile` to build all examples in release

### minor change
add two `eprintln!` in `inbreeding.rs` to show the experiment parameters

there was some missing parts from recent commits and also a dead link to `setup::setup` which is now `zk::setup`.

as per title

this MR also adds `nu --version` to the output of `make show`, to allow better debugging in the CI.

this MR splits the `fmt` rule of the `Makefile` into `fmt-check` and `fmt`, where `fmt` does the actual formatting and `fmt-check` only checks for bad format.
