4812: Allow `MEILI_NO_VERGEN` env var to skip vergen r=irevoire a=dureuill
- vergen checks the state of the `.git` directory to embed commit information into the `meilisearch` binary and the `cargo xtask bench` invocations.
- This check unfortunately results in too many recompilation of the `meilisearch` binary.
- This PR allows skipping vergen when the `MEILI_NO_VERGEN` variable is present in the environment

4805: Log the time to index a batch of task r=Kerollmops a=irevoire
This was proposed by `@qdequele` in a private conversation and I think it’s a nice addition.

4769: Federated search r=ManyTheFish a=dureuill
# Pull Request

[Usage](https://meilisearch.notion.site/v1-10-federated-search-698dfe36ab6b4668b044f735fb40f0b2)
## What does this PR do?
- multi-search now allows a top-level federation object. When not `null`, the results of multi-search are modified to be a single list of results rather than a list of a list of results
- changed lifetimes around tokenizer et al. to be able to make hits one by one rather than using a vector
- adds `roaring` to Meilisearch itself. As the federated search happens at the Meilisearch level (reuses the search functions declared at the Meilisearch level + merge happens after the hits were created), `RoaringBitmap`s are needed to track the candidates: hits that were seen, all candidates.
- Refactor `make_hits` to allow for an individual, optimized `make_hit`
- Score details comparison no longer fail when sorting on different field names or target point (for geo)

4626: Edit Documents with Rhai r=ManyTheFish a=Kerollmops
This PR introduces a first version of [the _Update Documents with Function_ (internal)](https://www.notion.so/meilisearch/Update-Documents-by-Function-45f87b13e61c4435b73943768a490808). It uses [the Rhai programming language](https://rhai.rs/) to let users express the modifications they want apply.
You can read more about the way to use this functions on [the Usage PRD Page](https://meilisearch.notion.site/Edit-Documents-with-Rhai-0cff8fea7655436592e7c8a6de932062?pvs=25). The [prototype is available](https://github.com/meilisearch/meilisearch/actions/runs/9038384483) through Docker by using the following command:
```
docker run -p 7700:7700 -v $(pwd)/meili_data:/meili_data getmeili/meilisearch:prototype-edit-documents-with-rhai-3
```
## TODO
- [x] Support the `DocumentEdition` task in dumps.
- [x] Remove the unwraps and panics.
- [x] Improve error codes for the `function` parameter.
- [x] [Update Rhai to v1.19.0](https://github.com/rhaiscript/rhai/releases/tag/v1.19.0) 🚀
- [x] Make it an experimental feature (only restrict the HTTP calls).
- [x] It must be possible not to send a context.
- [x] Rebase on main.
- [x] Check that the script cannot do any io.
- [x] ~Introduce a `Documents.edit` action or~ require the `Documents.all` action.
- [x] Change the `editionCode` to the clearer `function` field name in the tasks.
- [x] Support a user provided context and maybe more (but keep function execution isolated for reproducibility).
- [x] Support deleting documents when the `doc` is `()` (nil, null).
- [x] Support canceling document edition.
- [x] Multithread document edition by using rayon (and [rayon-par-bridge](https://docs.rs/rayon-par-bridge/latest/rayon_par_bridge/)).
- [x] Limit the number of instruction by function execution.
- [ ] ~Expose the limit of instructions in the settings.~ Not sure, in fact.
- [x] Ignore unmodified documents in the tasks count.
- [x] Make the `filter` field optional (not forced to be `null`).

4717: Implement intersection at end on the search pipeline r=Kerollmops a=Kerollmops
This PR is akin to #4713 and #4682 because it uses the new RoaringBitmap method to do the intersections directly on the serialized bytes for the bytes LMDB/heed returns. More work related to this issue can be done, and I listed that in #4780.
Running the following command shows where we use bitand/intersection operations and where we can potentially apply this optimization.
```sh
rg --type rust --vimgrep '\s&[=\s]' milli/src/search
```
