Fix packaging and settings facts in the docs

`docs/installation.md` claimed the full package contained every extra. It
pulls `docling`, `voyageai`, `cohere`, `zeroentropy`, `cross-encoder` and
`tui`, so `jina`, `s3` and `ingester` need installing separately. Without
`jina`, `provider: jina-local` falls back to no reranking. Anthropic is not
built in, and only the slim Docker image is published.

`docs/tuning.md` pointed at `claim_timeout_s`, which `WorkerConfig` now
rejects.

 - `Store.set_haiku_version` stamps the store's own config into a recreated settings row instead of the process-global `Config`.
 - `check_source_accessible` returns `False` for a URI it cannot resolve (unparseable host, unreadable path) instead of raising and aborting a full rebuild.
 - `evaluations run` opens the database read-only outside the population phase, so an embedder identity differing from the stored one warns instead of aborting the run.
+- `docs/installation.md` documents the `jina`, `s3` and `ingester` extras, names the extras the full package actually pulls, drops the removed MixedBread AI reranker, and no longer lists Anthropic as a built-in provider.
+- `docs/tuning.md` no longer points at the removed `claim_timeout_s` setting.
